Add an input method module supporting the Wayland input method protocol.
In v2:
- Missing call to ecore_wl_shutdown() in im_module_shutdown()
- Access the already stored 'wayland globals' with ecore_wl_globals_get()
- Fixed compilation by adding -I(top_srcdir)/src/efl to CFLAGS
- EFL formatting fixes
