Add Syntax Highlighting (this will take a few seconds, probably freezing your browser while it works)

/*
Please note that nearly this entire script is borrowed under a BSD Lisence from Ivan Sagalaev and his
collaborators (url: http://softwaremaniacs.org/soft/highlight/ ). Four things were contributed by the
grease monkey author:
1. The grease monkey comment block at the top, this comment block, and the two comment blocks
corresponding to the next two noted changes.
2. The call to the initHighlightingOnLoad() function, immediately below this block.
3. The GM_addStyle() function calls (the styles were borrowed from the test.html page given with the
original source for the borrowed script)
4. The original script contained a function called escape(); this function was renamed
to syntaxEscape() to avoid overloading a Javascript built in function and (hopefully) saving a lot
of developers a lot of headache over namespace collision.

/*
The following line specifies what languages will be searched for and highlighted. No parameters
will search for any. The options are python, html, css, delphi, perl, php, java, cpp, ruby,
javascript, vbscript. Only HTML and CSS are highlighted by default.

The following lines are the CSS styles for the highlighting. By default, any languages highlighted
will be displayed with the same styles.
