Change the GUI a little bit

Removed the launch of the ELF Compiler window at startup. Instead of it,
I added a menubar item called "Compiler", and within it a menu item
called "ELF Compiler", wich will launch the window.
- Fixed OpenGL renderer LoadVertexArray & DrawArray.
- Improved SPU SCs.
- Renamed mem_ptr_t -> mem_list_ptr_t, mem_struct_ptr_t -> mem_ptr_t.
