Use const everywhere that makes sense
return const variables when it makes sense
const functions and variables again, where it makes sense
No raw access and modifications to protected members
Move template definitions to tcc file
idk how I feel about this one
* Breakout rest of the enums from dcommonvars
so we don't have to deal with merge conflicts
ePlayerFlags is not a scoped enum, yet, due to it's complexity
* address feedback
* make player flag types consistent
* fix typo
