WIP: Moved sources int src/, separated most of the source code from Perl.

Browse source 
The XS was left only for the unit / integration tests, and it links
libslic3r only. No wxWidgets are allowed to be used from Perl starting
from now.

// The policy of all AGG containers and memory allocation strategy
// in general is that no allocated data requires explicit construction.
// It means that the allocator can be really simple; you can even
// replace new/delete to malloc/free. The constructors and destructors
// won't be called in this case, however everything will remain working.
// The second argument of deallocate() is the size of the allocated
// block. You can use this information if you wish.

// Single object allocator. It's also can be replaced with your custom
// allocator. The difference is that it can only allocate a single
// object and the constructor and destructor must be called.
// In AGG there is no need to allocate an array of objects with
// calling their constructors (only single ones). So that, if you
// replace these new/delete to malloc/free make sure that the in-place
// new is called and take care of calling the destructor too.
