move help up to the begining as in core modules, start private function names with an underscore and remove some meaningless intermediate variables

CHANGELOG
- added edit and add links to the glossary overview page for quick maintainence of terms
- added alphabet bar across top of overview page for quick navigation.
- the 'complete' link form of showing matches has been enhanced and the name has changed (requires re-savign of your admin page). we now use the HTML <acronym> tag for its intended purpose.
- trying to strip al tags out of the popups but the <br /> tag is stubborn in my experience. still outstanding
- added support for linking to the glossary terms from those search results produced by trip_search.module

improved error msg if admin has not configured a vocab

improve stylization of the overview page

removed some dead code

use the same long help text conventions as it is in the core, and add short and long filter tips (which are the same for now)

 - use proper linking in help texts, as in code
 - add some code to the filter function to inject the required CSS
   to the HTML header at the first time the filter runs
 - provide a clue on the enabled glossary module on the filter settings
   page, and point the admin to the detailed settings panel (it
   seemed that people had a hard time to find the glossary settings
   in the past)

 - only run the synonym query once on a page, and not once
   per string per term
 - use pass-by-reference to reduce memory usage, and only
   compute those substrings we need also reducing memory usage
 - improve on speed by using string functions instead of ereg()
   (measured in a simple test that it is 1.2 times faster)

My last commit introduced a bug in not taking the original string into account (for opened link checking). This fixes the problem with taking the approach of a 'moving window'. Further performance improvements later.

-Improve code readability by a lot of reorganization
 in the filtering code.
-Add a new feature to replace all occurances of a term
 and not just the first one (the default is still the later)
-Update CHANGELOG and README accordingly

Move the SQL query out to a caching function so it will not be run N times (N being the number of strings to filter). Add direct support for linking to the detailed information nodes (taxonomy page). Simulate that taxonomy page via a custom URL, since we need proper breadcrumbs, and the taxonomy module does not allow us to hook into the page display. Also done a bit of a reorganization: converted if-elseif-else statements to a switch()

add support for full linking, so the whole match is put into a link, and therefore it is easierr to click on it, and get more information

Update CHANGELOG, README and TODO. Merge INSTALL with README, so we can get rid of multiplied information. Get rid of unused css file.

Use a definition list to mark up the glossary, since it is by nature a definition list. Also add a new feature to attach nodes to the term to provide detailed background information on a term (the description only allows for a short explanation)

dramatically improve translation support on this module (now complete), plus add access check to the suggestion on administrating the glossary

- Theme system updates: theme() function return their data now.

superscripted as it messes up the text's vertical spacing.

Regressing this back to 1.19 version. New version has a few issues that I don't have time to patch for a couple of days, hence will put it in my sandbox instead. Sorry for the inconvenience.
