Mime Type Drop Down

[gleporeNARA]

Splitting this out as a separate issue. Below is a quick and dirty extraction of the mime types currently listed in PRONOM. I think it's too big to stuff into a drop down. Probably needs some more thought. I was thinking about something like the font dialogs in LibreOffice, where the most used are at the top, and then a bulk list below.

For a list of most active mime types, see:
