Further Bug Fixes and Improvements to 2.0

+ Set the default VCS tag name back to {version}.  Accidentally committed {name}-{version}.
+ If the old-style export command is already surrounded by quotes, remove them.  They will be added back by the interpreter.
+ When getting a Version object from a VCS tag, use the new regex provided in the settings.  This is required if the VCS tag name has been changed so we can always match the version part which we need to make a Version object.
