Flashhack - New LT1 flash tool

[NomakeWan]

alright new version is up
- Remember last selected ECM as default because most people dont use it for more than one ecm
- Provide some fixes and a menu option to select a new ECM (so you don't have to restart the program)
- Add a workaround for the E-Side comms patch so the recovery rom works
- Add unique vehicle identifier to EE because nomakewan actually owns two LT1s for some reason
- Use .bin extension properly in save/load dialogs

Sweet, thank you for the unique vehicle identifier code! Tested it by reading both cars, and it saved the unique IDs just fine. Will need to actually make some changes to see if it recognizes them too but glancing at the code it should do that without any issues.

That said, this time I did manage to catch that "unable to reboot T-Side" error on the '94. I've attached a log to this post.
