Sometimes when creating a thumbnail image, getimagesize doesn't return
a value for bits per pixel on certain gifs.  This creates warnings in
the logs when approximating the required memory consumption, and also
refuses to create the thumbnail.  We can check the mimetype of the
image when 'bits' is not set, and when it's a gif, just assume the
maximum value (8 bpp).

When a user has many views shared with them, the view_search query
may exceed mysql's max_join_size and cause an unrecoverable error on
a user's dashboard, among other places.  Replacing a bunch of these
outer joins with subselects fixes the issue, and in a few tests on a
large postgres db, also improved performance.

In IE, when dragging a blocktype image into the content area of the
view editor, the image appears to slip underneath the white box saying
"This area shows a preview of what your page will look like..." and
then out the other side again.  Setting the z-index property on the
element containing blocktype list fixes the issue.

When dragging a blocktype in the view editor in IE, dragging it very
slowly usually causes the block to suddenly disappear, and the cursor
to turn into a crossed circle.  If you let go of the mouse, the
blocktype image appears at the cursor, and clicking the mouse again
will drop the blocktype.  This can be fixed by disabling IE's default
startdrag function.

Updating a site menu item and swapping it from an external url to
a site file or vice versa was failing to create the correct type of
link on account of incorrect parameters. Unfortunately this can't
fix existing muddled links, as it has no way of knowing whether the
url value or the file value in the database is the one to use.
