Fixed bots being unable to weld small or thin func_weldable objects correctly
Config in nsbots.ini is no longer case-sensitive
Added safeguards when parsing nsbots.ini to prevent crashing and highlight issues to user. This fixes an issue which would cause bots to have godlike difficulty on the easiest setting if the ini was malformed
Made mp_botautomode and mp_botcommandermode default to "1" (auto-fill teams and allow bot commander)
Fixed an issue which prevented bots using certain lifts (e.g. by alien hive in co_niveus). Also fixed a potential infinite loop when detecting door triggers
Fixed an issue which caused marine bots guarding the base to spin and freak out
