feature request: multiple selection of languages

[adamwong246]

For instance, allow me to select from projects that use CoffeeScript and/or Javascript.

Makes sense, but not really sure how the UI for it would look...

It'd probably be easy to do this with the Chosen library.

@AustinDizzy Nice! The tags-like multiple select would be great.

I'd also like to filter by templates (e.g. Python-powered, using Jinja2), and probably also by license, when we're at it. 😏

@adamwong246 Would you mind adapting the issue title accordingly?

A PR is welcome on this if someone is up to it, I will leave this issue open.
