#173 Generation of inherited class doesn't preserve user code changes

[eanon]

Hello. In changelog about 3.01.68 RC1*, I read "Generation of inherited class (F6) preserves all user code changes now (so it can be used more than once) (spedgenius)", but trying with wxFormBuilder 3.01.70 and the last 3.5.1 RC1, it erases my added Python code everytime I hit F6.
