[Pasdoc-main] PasDoc handles now generics (both FPC and Delphi flavor) nicely

[Michalis K. <mic...@gm...>]

Hi,

I recently converted my game engine to heavily use FPC generics, so of
course I needed PasDoc to properly support them too :) Done. Both FPC
and Delphi generics flavor is now fully handled by PasDoc as far as I
know. Both specialization of generics, and declaring generic classes,
work.

Also, hierarchy of FPC FGL containers (TFPSList, TFPGList and friends)
is added to the default knowledge of PasDoc "external classes
hierarchy", so they'll show up nicely in "Class Hierarchy" diagrams
too.

The whole thing was tested on (much extended now) tests/ok_generic.pas
(and my sources).

There are of course little things to improve (the types on type
identifiers list "<T1,T2>", could be parsed better and added to the
internal types of the class; OTOH, they will have to be treated
specially anyway, as these types are not defined at the generic
declaration --- that's the whole point of generics, after all). But I
think that the result looks acceptable already :)

Enjoy :),
