Add ':' inside translatable (Part 1 of 2)

Punctuation needs to be included in translation since punctuation differs
depending on the language.  Along with moving ':' also replaced &nbsp; with
blank space insde trans tag.    The initial review grew too large, so this
patch has been broken into 2 reviews.  Part 2 will cover the files in
openstack_dashboard/dashboard/project while Part 1 will cover the rest.
