Thomas Goyne 76f0afecaf Eliminate pointless wxDialog subclasses 
A lot of the wxDialog subclasses don't actually override any virtual
functions, so there's no particular need for them to be subclasses at
all, and wxDialog's vtable is so huge that they actually contribute
measureable to the size of the executable.
