* Implemented a proper initializer for the mask tables (s_nMaskTable has been removed).
* Implemented write methods in 'bf_write'. There are still some missing methods; there have to be added in later.
* Documented most functions.
* Put initializer values inside brackets.
* Put logical AND conditions within parentheses.
* Put assignments within conditional statements within parentheses.
* Mark unused variables as such to suppress compiler warnings.
* Fix vftable shadow warnings caused by ConVar::CreateInternal (does not implement, only interface. Renamed to yield desired behavior).
* Fix 'never' initialized class members for 'CCVarIteratorInternal'.
* Return values in interface vftables that cannot be pure virtual.
