Bug 20109: Make "Remove" translatable when adding a fund

When a user has been added to the fund, the link to "Remove" that user
is not translatable.

Test plan:

1) Install language xx-YY
2) Go to Home -> Administration -> Budgets -> Funds -> Add Fund
3) Add a user to the fund
4) Notice how the "Remove" link after the user's name is not translated
5) Apply patch
6) Look in xx-YY-staff-prog.po, and if needed, translate the msgid
   "Remove"
7) Update and reinstall the language
8) Do 2 and 3 again. The "Remove" link should now be translated.
