Bug 7082: Template improvements for better translatability

Problem:
/cgi-bin/koha/admin/aqbudgets.pl
<label for="show_mine">Show my<br /> funds only</label>

This gets broken into 2 strings for translation which makes it very hard for
translators to make sense of it.
Patch removes the line break.

This patch removes the linebreak and has no ill effects that I can see, even
on a small screen. I'll attach before and after screenshots in Bugzilla.
