ModNodeHandler bug fixed.
Merge remote-tracking branch 'upstream/dev'
Fixed artifact in .gitignore
Fixed major typo ModSelectionController.cs (When updating a single mod is would update ALL mods flagged at outdated. Letter-case matters...)
Added Version field transfer to ModNode, so update checking will work with KerbalStuff (or any site using version instead of ChangeDate)
Tweaked KerbalStuff handler to allow for null version info (possible for beta users with mods install prior to this fix as well as adding URL after install from local archive.)
Roller version to 2.0.0.9
