- cmake/make/scons didnt define INTERNATIONAL when buidling blenfont

- BLF_lang_init used confusing IFDEF's, unlikely this was well tested. Split this into 3 functions for Apple/Win32/Unix, Unix uses BLI_gethome_folder(), cant test others, ideally they should use BLI_gethome_folder too but needs testing.
Possibly each os cant be made to use BLI_gethome_folder and the separate func's can be removed (please test).

- units, hectometers were displayed wrong.
