Update to Harmony 2.0

[Ijwu]

PPML is stuck on Harmony 1.2 for the time being. Harmony 1.2 has been deprecates and 2.0 is the suggested route forward.

There is one main issue with this: Harmony patches for 1.2 are not inherently compatible with 2.0. Meaning this could break compat... again. I'm loathe to commit to doing that so another way will have to be made available.

Options:

• Ship with Harmony 1.2 for those mods which use it anyway, but port PPML to 2.0.
• Create a compat layer for 1.2 <-> 2.0.

I've tried it with modnix, from commit df9a60 to commit 1a03c1, and gave up.

The bridge part is independent from other code so you may take that if you want to give it a try. Code: Compat layer (first attempt), coexistance patch (second attempt).

My conclusion is that both Harmony cannot co-exist in same AppDomain, and obviously Harmony won't work if it is loaded into a separate domain. If I am to try again I'd properly clone Harmony 2.0 and mix in my bridge code.

Good luck. If you can solve the problem, you will be the hero for many modders.
