Include lightgrep scanner results in "User-supplied regular expressions"

[hannahlwang]

Based on my review of BR, I would like to have results from the lightgrep scanner included in the “User-supplied regular expressions” filter in the Review Dashboard, which is currently limited to the results of the find scanner. It might also make sense to deduplicate these results, since the results of both scanners (if both are run) will be redundant.

Thank you, Hannah, and good timing! In Bulk Reviewer 0.2.0 (out today), features in both lightgrep.txt and find.txt map to "User-supplied regular expressions". If BR finds both lightgrep.txt and find.txt in the feature files directory, it will read only from lightgrep.txt, which should get rid of the duplicate results.
