Optimizations for gs_ajax_utils.js

[zcarter]

I am unable to email these changes as I am at school, and I don't have Subversion write access (and the school computers don't have SVN anyway).

The changes are:

• Changed multiple concatenations into creation of lists (they are joined when returned). This is faster as in Javascript, strings are immutable.
• Changed postfix increments to prefix increments where possible; slight performance boost.
• Changed multi-line functions into one-liners where possible (avoids variable allocation, etc.)
• Fixed inconsistencies in coding style (all four-spaces instead of mixed, whitespace added, etc.)
• Removed unneeded whitespace.

Included is a diff file, and the actual file itself.

Fixed newOpenTag. Fixed a coding style inconsistency.

Updated gs_ajax_utils.js again; coding inconsistency with an if statement and added a join() call to newOpenTag.

Several optimizations have been made but as this is only used in one minor feature we will move this back to the 3.06 release.
