Better catch when vcs programs not installed. #86

Check if vcs commands exist before running commands. Cache the result so that the check doesn't happen for every file (if the user installs git or hg, they will need to restart runmanager or the compiler subprocess for saving of vcs info to start working).

Should address https://github.com/labscript-suite/labscript-suite/issues/66

Another old PR that should have been merged a long time ago. Looks fine to me.
