+ pgenutil.pas:
add a procedure which adds a type symbol to a non-Delphi-mode generic class or record which has the same name as the unit global dummy symbol for that generic. I don't know why I had that idea earlier as this will simplify some of the conditions in the parser again (I haven't changed these yet, but I hope to do that at least when I start working on generic functions).
* pgenutil.pas, generate_specialization:
correctly handle "specialize TSomeGeneric<T>" as method parameter in a generic with the newly added rename symbol
* pdecobj.pas, object_dec & ptype.pas, record_dec:
call the procedure to add the rename symbol (the procedure checks whether the mode is correct)
* ppu.pas:
increase PPU version so that we don't use non-Delphi mode units with generics, but without the rename symbol
+ added tests:
the one in webtbs are for classes/objects and those in test are for records
