- Remove obsolete sample targets
- Restore and build solution (.Lean) instead of projects
- Read version from common.props, compare with latest changelog version
and fail if not equal
- Keep PostFix separate from version (AssemblyVersion may not have
a postfix), so the postfix will go into the package version and
file name as well as the informational version (visible in file
properties dialog on Windows)
- Add "ElectronNET.Core " as prefix to GitHub release names (to
disambiguate with earlier versions)
