Move table actions partial to a component

This partial was going to get too complex since in some places we've got
different texts, different URLs or different confirmation messages.
While we should probably try to be more consistent and that would make
the partial work in most cases, there'll always be some exceptions, and
using a partial (with, perhaps, some helper methods) will become messy
really quickly.
