Bug 766: Remove CGI::scrolling_list from aqplan.pl

Bug 766: Remove CGI::scrolling_list from aqplan.pl

This patch removes 3 occurences on aqplan.pl

To test:
1. You need a budget and a fund
2. Apply the patch
3. Go to Aquisitions, click on your fund
4. Select one of the options on pulldown Planning
e.g. "Plan by months"
5. Now to the left there are two boxes, Filter and Export

a) Filter: (1) pulldown below 'Select planning type'
check that works selecting other values and submit
This pulldown showed originally code types,
untranslatable BTW. Added a TT block to allow translation
and shows legends that match Planning pulldown, but not
the order.

b) Export: pulldowns for filetype (2) and delimiter (3)
Those have originally one value each, and for me Export
does not work, before or after patch, but check that
pulldown exist.

Notes:
A) 5.a) I can change de order of main Planning pulldown,
is harcoded. The values for Filter pulldown are sorted on
aqplan.pl. Is one or the other.
If desired, TT block can be moved to includes/budgets-admin-toolbar.inc
(where hardcoded Planning lives)

B) 5.b) Moved 'Export' legend inside it's box, like Filter.

C) Finally: there is something strange, before or after patch.
There is an empty option 'Planning by " if you select planning
using main pulldown, it disappears if you select planning using
Filter (not a mistery, using Planning fills $auth_cats_loop,
using Filter submit button does not)

Looks like this needs more work, but no regressions found that were
caused by the patch.
Passes tests and QA script.
