[WG: I18N & L10N] Dynamic localization via database backend for 2.8

[John Bush]

This is for the work in.
http://jira.sakaiproject.org/browse/SAK-18678

The kernel changes are in a branch, and the front end tool is in
contrib.  I made 2 screencasts to show/talk about it more.

I'd like to get both of these things in 2.8.   Technically, the front
end could live in contrib if need be, but the whole thing is a lot
more useful with the front end tool there.

back end - http://jira.sakaiproject.org/browse/KNL-563

I've deployed this stuff to a test server, if you want to touch/play
with it, you can do that here.   http://72.44.205.11:8080
