Bug 27397: The description input field when defining numbering patterns is too short

Test Plan:
1. go to the serials module
2. click on manage numbering patterns in the left hand navigation
3. add or edit a pattern
4. check the description field is as short as the name field, but can
take much more text
5. add patch
6. repeat steps 1-3
7. check the description field is larger than the name field (it should)
