v0.3.0: Show dedup/title values (#25)

Adds support for multiple globals! Now global analysis types must specify the GlobalID field, which will be used as the name to import the module as. This is a breaking change from prior versions of the tool (hence the minor version bump) so be sure to update your global analysis types before upgrading to this version.

Additionally, this version has rules output their dedup and title strings when the appropriate functions are present, and will now automatically check for analysis types in the global_helpers directory (relative the the current working directory the tool is being run from).
