[Weaver-framework] Some suggestions...

[Cojocaru Alexandru]

Here are some suggestions, feature requests and bug reports:
- When adding a new pair of files (.c/.h) with `weaver' it should *not* add an
  #include "filename.h"
 in all others .h files. It should at most add an `include' statement in game.h;
- It would be nice if you used the autotools 
(https://gnu.org/software/autoconf);
- I don't need fullscreen, can you add the possibility to specify screen 
resolution?
- Use pkg-config with libpng too, it fails to compile under Parabola 
GNU/Linux-libre
  otherwise;
- Put `-Wl,-as-needed' in CFLAGS, in thiw way libraries not needed will not be 
linked;
- The correct way to declare global variables, is to put an
   extern int foo;
  in `some_file.h' and
   int foo;
  in `some_file.c'.
- Under GNU files ending in ~ are backup files. Weaver should not remove them.
