1.2.2: Merge pull request #18 from msarahan/user_path_fallback

This release attempts to fall back to user-level directories for shortcuts when system-wide directories are off-limits.

This situation comes up with Anaconda and Miniconda: if the initial installation is system-wide, then shortcuts will be placed in a location that requires elevation. This release should address that condition: shortcuts will instead be installed to the current user's personal collection of start menu shortcuts, and a warning is printed to the console.

This should fix many failed conda update calls.
