Tons of fixes! Yeah!
Add lots more error checking
Logging now properly supports multiline strings
Fixed an issue where crashes during option parsing but after enabling logging would simply append old old logs rather than making a new one
Fixed issue where exec option always crashed
Fixed 2 issues where clua would always crash (moved some preparse code back above function declaration)
Fixed issue where IFVAR and IFNVAR would incorrectly report their line number
Changed 'Enable logging' message's level to DEBUG from OKAY
