[VimeoBridge] Add new bridge

[logmanoriginal]

Add new bridge for search results from https://vimeo.com

References #932

This bridge doesn't support filtering (yet). The "type" parameter should be split into categories for filtering to work properly.

Vimeo already supports RSS or why do we need this bridge? https://vimeo.com/USERID/videos/rss

Vimeo doesn't support feeds for search results. Find more details in #932.

I don't use Vimeo personally and the original request has gone stale, so this PR is left open in case someone shows interest. Until then it remains unfinished and will be closed eventually.

I'll add this bridge should sort by date, so it returns latest search result.

Items are now sorted by date (thanks for the feedback @AntoineTurmel).
I don't think there is any reason to hold this bridge back anymore.

Since Vimeo's own feed is too poor (contains no rss entry title), I first tried online webparsers (fivefilters.org, morss.it, politepol.com) unsucessfully. Now I see, that RSS bridge does not work either:

Bridge returned error 400! (18620)
