+ Added a construct that unifies all things constructed by the lib
+ and needed to represent a program: irprog.ch
+ This contains a list of all types as well as a list of all ir graphs.
+ I added calls to initialization and constructors so that this is constructed
+ automatically. I changed firm.c, type.c, irgraph.c and ev. more.
