+ - Rewrote constant folding optimization pass for the parser.
+ - New additional dead-code-elimination-consatant-fold pass for
+ if statements whos expression can be evaluated at compile-time
+ (allowing the if/else branch to be entierly elided at compile-time).
+ - Added support for columns in error diagnostics.
+ - Limit corrector to <= 16 byte strings.
+ - Improved hash function for hashtable (old hash function had 15% error,
+ this speeds up compilation)
+ - Improved performance of in-house allocator with branch-hinting, speeds
+ up compilation of Xonotic by 3 seconds!
