Fixes for attached debugging and related improvements. (#784)

'launch' and 'attach' modes are working with these changes. The root problems were related to the version of the attached project not being detected properly and file paths not being correctly calculated when attached. The networking code that had version-dependent behavior is now a bit more robust and won't break if minor versions were to ever exceed 1 digit.
When using 'attach' mode, the version info wasn't available at all, causing most (all?) network messages to be ignored.
