Bug 20165: Changed uppercase letter to a lowercase letter in the patron search search fields under the plus option.

Changed "Street Address" to "Street address" in the patron search search
fields under the plus sign to fit Koha's capitalization rules.

To find this change:

1. Go to Patrons and switch in the search to search patrons
2. Click on the plus sign
3. Check "Search fields" pull down
4. "Street Address" should now be "Street address"
