Disabled package restore (no packages, plus vs handles this nicely)
Removed extra tasks, and condensed them into Node for GetVersion and InstalModule.
Added logo to repo, packages to ignore.
Updated version check to support looking at the nuget repo for the latest version, so that NCapsulate can still rev packages even if the underlying dependency has not had a version bump.
Ignore api.key
Updated assembly info, fixed up nuget powershell scripts.
