* Updated gba_db.bin Builder to v2.1, adding some important fail-safes and fixing some nasty bugs.
* Updated Makefile to create releases as ZIPs instead of 7Zs and include the gba_db.bin file in releases.
* Updated gitignore to allow necessary files for gba_db.bin Builder to be added to the repo, among other changes.
* Moved script and necessary files to a new "tools" folder. The resources folder is now used for files that facilitate releases, such as "safe" versions of gba_db.bin.
* Made a few changes to open_agb_firm.c to prepare for full gba_db.bin integration.
* Updated README to reflect the new changes, among other changes.
