Bug #1006634, part 3

Replaces existing group/view.php urls with calls to
group_homepage_url, in a bunch of places where only a minor change is
required to fetch the urlid property, and where it is clear it will
have little impact on performance:

- My groups block
- Cancel button on group delete
- Redirects after joining a group or inviting a user
- Group tab of the admin stats area
- My groups section of the profile sideblock
- Redirect after submitting a view

Bug #1006634, part 3

Replaces a bunch of hardcoded group/view.php urls with calls to
group_homepage_url, in a few cases where it is obvious that the urlid
property is already part of the group object available at that point.

Bug #1006634, part 3

Adds a new function to generate a group homepage url from a group
object, and uses this function instead of a hardcoded url in the group
lists on Find Groups and My Groups.

While commit 0af8ce9e makes it so new copied
journals etc shouldn't get lost, there are accounts that had copied journals
from before commit 5e07db54 went into effect,
and are now hence hidden. This new commit works around that so that the option
to enable multiblogs is visible if it is somehow disabled for someone with
multiple journals, rather than just being ignored for everyone with multiple
journals. A discreet notice has been placed on /artefact/blog/view/ so that
the user knows.

view/view.php, which are expected to contain valid urlid values, and

homepage urls on the edit group page, and portfolio page urls under
Edit Title and Description in the view editor.

In some cases, it's useful to put explanatory text or html before a
pieform element, but after the label.  A 'prehtml' field is added to
the pieform renderers to achieve this.

This will be useful, for example, when the user is able to edit the
very last portion of a url, but not the full url.  The initial,
uneditable part can be displayed before the textbox, so that the user
is aware of the context for the field they're editing.

Bug #1006634, part 1

Clean urls can be enabled at any time.  Initialisation for existing
users should not be tied to a site upgrade, because it is slow, and
most sites won't ever enable it.  Instead, add an admin page with a
button to regenerate all clean urls based on existing usernames, group
names, and page titles.

When generating new clean urls, transliteration of utf8 characters
works better when the locale is set appropriately, so it will be
useful to be able to change locales without having to change the
current language.

Bug #1006634, part 1

Whenever a new user, group, or portfolio page is created and clean
urls are enabled, ensure the urlid field is set to something vaguely
sensible.  Ensure new user and group urlids are unique, and ensure new
view urlids are unique for the owner.

Bug #1006634, part 1

Given a string possibly containing characters that are invalid in a
clean url, return a new string, of the allowed length, containing only
valid clean url characters.  If converting utf8 to ascii,
transliterate using the iconv function.

Part of bug #793308

Adds a config.php option which lets users change their theme (for
browsing) via a drop-down on the Settings page.  The allowed themes
are the same set accessible to the user when the viewthemes option is
availiable.  Any theme which is restricted to one or more institutions
in its themeconfig.php file is not available in the drop-down unless
the user is a member of one of those institutions.

Part of bug #793308

If a user has the 'theme' property set in their account preferences,
this is used instead of the site or institution's theme.

The LiveUser::reset_institutions() function, which recalculates the
institution theme, is now called in place of LiveUser::update_theme()
whenever a user's institutions have changed.  reset_institutions() now
calls update_theme() if the user is a LiveUser.

The Theme constructor expects a triple (basename, logo, stylesheet),
which is passed by the User::get_themedata function.  But the three
properties are stored separately in the User object.  If they are
grouped together, then it will be easier to switch themes in and out
at a later date.

The three properties are combined under the 'institutiontheme' name,
to make it clear that they are defined by the user's institutions, and
to distinguish them from the user's own theme preference.

This requires a slight change to code for setting a view theme on view
creation, where only the basename property is allowed, because custom
themes with logos & stylesheets are not yet available as view themes.
