Add fallback to Drastic BIOS and fake firmware when not provided (#105)

Browse Source 
* Generate a simple non-bootable firmware when not provided.

* Expose Username and Language into settings dialog.

* Add firmware overrides for more settings. Also make override optionals when a firmware is provided.

* Refactor firmware settings into separate dialog.

* use usernameLength instead of u16Username.length() (#3)

* Fix curly braces code-style.

* Fallback to FreeBIOS when BIOS files are not found.

* Add sources of drastic bios files.

* Handle frontend language and set default username.

* Add missing configuration variables.

* Allow load to progress when firmware/bios is missing.

* Use new arm toolchain to build drastic bios.

-- Info --
This archive contains source code and assembly for a custom BIOS replacement
for the Nintendo DS system. This code is in no way affiliated with Nintendo
and is not derived from Nintendo's BIOS implementation but has been implemented
using publically available documentation.
It can be assembled using the included Makefile along with a proper ARM gcc
toolchain. Change the first four lines to point to the proper toolchain of your
choice.
