Sigma Dimensions v0.11.0

First release since adoption of mod by R-T-B, who will also be administering PR's for the community under the ARR license.

Changes:

1.) Integrated a PR from @CashnipLeaf, which fixes an error in which world's name "Kerbin" always had the ASL atmo pressure hardcoded to 101.325kPa. Also some performance refactoring by him, and general code cleanup for the modern era.

If you like the mod, please feel free to donate to @Sigma88 on the main github page.
