Add support for up to 72 gametypes
Closes #2900 (closed)
Code by @Mario ported from this patch that changes .m_flags
into a .gametype_flags
vector which upgrades the amount of usable bits from 24 to 72 which is 3 times that, due to the float -> array of 3 floats migration.
This patch was tested by @NaitLee before I updated it.
