small fix to admin links at bottom of overveiw page
remove CHANGELOG file. use CVS instead. there is a link from the project page at drupal.org

improve themability of items on the overview page

added blocks for each vocabulary with vocab name and description (by gerhard)

i'm halfway through adding a block for searching the tern names and descriptions in the glossary. i have to commit now before i get pulled away. sorry for the commented out code.

We still used drupal_specialchars, which was removed recently. Actually,
escaping is now done within the l() call, so we do not need to do it at all.
We just call check_plain for acronym links, as that is the only place we
generate HTML directly.

some good fellow forgot to make these menu item names actually translated in the help (ported from 4.5)

restore old functionality of displaying *the* glossary, if there is only one glossary available, without choosing one to display from the one item list, plus:

 - link to the main glossary page in this case and
 - fix this linking so that it is path alias friendly

All ported from 4.5

        glossary in /glossary

No functional changes.

Also fixes issues 12936, 10645 and 9457

The code-style.pl script does not produce any output anymore. Unless I have made some dumb mistake, functionality should be exactly the same as before this commit.
