* Fix DSI build. Now works correctly on DSi.
* Fixed soft reset into boot.nds. Now works on both DSi and flashcarts.
Also fixed for theme reset.
* Fixed soft reset into GBA mode. Was using libnds's broken swi call.
Replaced with modified version that isn't broken.
* Fixed warnings generated during compile.
* Removed old LD/Specs from arm7 folder. This is needed to allow proper
arm7 entry point for TWL_FIRM compatiblity on 3DS. Didn't seem to break
DS mode copy so a DSi specific build of arm7 make file is not needed at
the moment.
* custom banner added via banner.bin and -t ndstool command.
* Flashcart build now uses -h 0x200 command for better compatiblity with
older homebrew launchers/flashcarts.
