Allow import com.example.blah.* with given

[japgolly]

Instead of this:

import com.example.blah.{*,given}

how about we support

import com.example.blah.* with given

?

[bishabosha]

does this only apply for given Foo, or replace all commas?

[som-snytt]

Also another opportunity to work in import p.* for given.

Arguably, implicits are Scala's original sin.
