Many functions are modifying internals of CBooModel and const-casting
is performed in order to work around functions being const when they
really shouldn't be.
This amends the function signatures in order to allow these functions to
exist without const_cast, making code much nicer to read.
Applies the override keyword where applicable to indicate visually where
member function overriding is occurring. This only targets
the RuntimeCommonB target as a starting point, which resolves around
900+ cases where the keyword could be used.
