Bug 24242: Display funds that the logged in user can access - suggestions

The design of this script is pretty bad and any modifications is a
challenge.
Here we are trying to display to display the funds available for the
logged in user. I did not understand previous code, as we are doing a
limit using CanUserUseBudget, I do not think it makes sense to retrieve
funds for a given library.
Also, I am wondering if the dropdown list in the filters has ever been
populated: budgetid_loop in the template *never* appeared in the history
of suggestion.pl (??)

Test plan:
Search for suggestions
Add/edit suggestions
=> The funds in the dropdown list should be the ones the logged in user
can use.
