v2.7.0b1 - December Pre-release

Many changes to how we do DPS / RR calculations have been made to better support the new Triglavian spool-up modules, courtesy of @DarkFenX! Additionally, we have started to use AppVeyor for Window builds instead of builds directly from @blitzmann's machine. Because of these changes, we are introducing a pre-release a few days before an official release for the December expansion to hopefully iron out any bugs that might crop up. A full list of changes will come with the official release early next week.

Also of note that OS X build isn't included in this pre-release due to lack of access to a build machine right now. It will be available for the official release.
