Updated Makefile to build for cantact/disco boards (build with make B…
…ULID_HW=disco, default cantact, if no arguments specified) Added (well, actually copied from CMSIS template folder) startup/linker files for stmf072 for gcc build Made LED GPIO ports selectable for each LED (still need to edit LED_GPIO_CLK by the user but at that point they should know what they're doing)
