Some extra tag options.

[Andy2244]

Really like the module so far, quick and easy to use.
Yet i have trouble emulating common scene naming schemes, so maybe some extra format virtual tag options could be added?

1. %year% seems to always output a range, even if its the same year. So a new %s_year% should always result in a single year output.
2. Something like a virtual %s_resolution% (short) tag. So "1280x720" will result in the normal "720p" string.

Maybe allow us to hand over a extra regex parameter or local string/format script, that is run just in between the format and final move/rename logic?
