Bug 6181: Remove CGI Scolling lists from C4::Budgets

As noted on bug 766 more cases of usage of
CGI::scrolling_list were imported into C4::Budgets
Even if we were not trying to remove usage of this
the C4 modules are not the place to generate markup
Most of these routines are noise as they are not used in
any current code but cause confusion and increase
maintenance overhead. They are removed

The sort dropboxes on order create are the only
references in current templates to these routines
they have been replaced by a select list generated
by the markup.
They can probably be removed too but their existence
although the option that causes them to be displayed
seems unlikely to be set. I've left them pending
resolution of some of the inconsistencies and
confusions surrounding Budgts
