Script now uses and imports a donor title database to prevent confusing rebooting / database resetting - no more "Dummy title database found"!
Explicitly check for A:/dbs/title.db to determine existence of title database (likely inconsequential)
Check if A:/dbs/title.db is valid
Check if any dependency files are missing and/or fail to install
Clean up SD card files for Alternate Exploits, menuhax67, nimdsphax
Catch double-backups (i.e. user tries to re-run script without Nintendo 3DS folder after already having made a NAND backup)
Troubleshooting also updated accordingly.
