Spoike 4974c57c2c Big fat-off commit. 
A few changes. Half-Life support is finally getting committed.
Some unnecessary filesystem code changes.
And there's code for nsapi - meaning we can embed FTE in a browser (firefox and opera on windows work).
A couple of CSQC changes, trying to move towards a final EXT_CSQC_1.
Revised ruleset format finally implemented.
Doesn't compile with msvc6 due to issues with libjpeg not being a clean library.
Presumably its fine in vs2005.
Your mileage may vary.
