Move Crunch to its own Packer, improve SmartE detection.

[HeroponRikiBestest]

All SmartE games use the Crunch packer from BitArts, which is what the BITARTS string check was actually checking for. Some non-SmartE software is also packed with Crunch, so Crunch was moved to its own seperate packer check.

SmartE generates an executable stub when you run it, which has SmartE in the executable properties. Added a check for this in case someone wanted to manually scan a stub they generated.

A Yara/PEiD check exists that works for all known SmartE games except Dungeon Siege 1, doesn't have false positives on non-SmartE executables packed with Crunch, and is long enough that there's virtually no chance of a random false positive. This check was added to the SmartE protection scanning. Thus far, it always occurs on the last section, so that is the first check. Fallback checks for specific known named sections are also included.
