Bug 13128 - Add span with id for logged in branch name, add hidden span for branchcode

It would be nice if there were a simple way to access the name and
branchcode of the currently logged in library, as well as the logged in
user via JavaScript ( via intranetuserjs ).

I propose the following:
1) Remove the whitespace surrounding the loggedinusername span
2) Wrap the logged in branch name with a span that has an id
3) Add the branchcode in a hidden span that has an id

Test Plan:
1) Apply this patch
2) Log into Koha
3) Inspect the html source code
4) Note the lack of whitespace within the tag <span class="loggedinusername">[% loggedinusername %]</span>
5) Note the logged in branch name is now surrounded by a span with an id
6) Note below that is a span containing the branchcode, also with an id.
7) Verify the branchcode span is hidden by default.
