Move account expiry from institution to site options; add theme, membership period to institution settings

Show an informational string about the password format. Don't show the descriptions of the form elements if an error occurs.

Make sure pieforms is always available, it tends not to be when doing the key part causing fatal errors. Oooold bug.

Now, table names (and other identifiers that could be confused with SQL kewords), should be put into SQL like this:

SELECT * FROM {artefact}

The braces are matched and expanded by DML now to include the prefix and be properly quoted, which means that tables like 'view' and 'group' don't need renaming (and nor should they, there's little reason why we should rename tables to get around such constraints).

This has removed a whole bunch of $prefix = ... and get_config('dbprefix') stuff, which makes things a little simpler yet again.

code

constants - SECTION_PLUGINTYPE, SECTION_PLUGINNAME, SECTION_PAGE -
which are used to build up the page help thing instead of trying to parse
the url.  I have only added these constants to pages that had page help,
it would be a good idea to add checks for them to file_content_check
and definitely add them in when they're missing

back to pieform configure function, fixed up param_retrieve to not
use REQUEST (as it reads cookies), but instead to read post and get
directly. added contextual help for login box

addresses, not just primary ones. Make sure that newly registered users
do not clobber existing e-mail addresses.

subdirectory properly.

CSS rules so they work as intended

* Redirect properly if the user is already logged in and hits the
  registration page.
* Removed debugging messages and descriptions on form elements for the
  first step
* Added the profileimage element to the step 3 form so users can upload
  immediately. This updates the quota properly
* Styled the step 3 form better, and make it display all of the element
  types properly.

likely some stuff still doesn't work properly...

institution

is set. If the registration request has expired, turf them out

bugs to do with the $SESSION -> $USER change.
