Bug 1021084

Description of problem:
When constructing a content view filter for Puppet modules, you're prompted to enter the module name and given a "+ Add" link to the right.  Each time you click it, a new "parameter" appears which enables filtering by author and version.  There's no obvious way to get rid of these new filters.

How reproducible:
Always

Steps to Reproduce:
1. Create a content view definition including a puppet module repo
2. Create a filter called "test", add the puppet module repo
3. Create a puppet module rule
4. Enter "stdlib" in the module name box
5. Click "+ Add" three times
6. Return to the filter view, click "Filter: test" at the top
7. Click on the rule again
8. Try to remove the two additional parameters

Actual results:
5. Allows you to create and save multiple blank parameters
6. Rule summary says: "Include Puppet Modules: stdlib, stdlib, stdlib"
7. Module name is missing from the top box, three blank parameters still listed
8. No remove button?

Expected results:
5. I expect that "+ Add" adds the module rule itself, not additional parameters.  Instead, perhaps always show a blank parameter row, that when filled in is added to the saved list.
6. "Include Puppet Module: stdlib"
7. Module name is shown, only one stored parameter shown
8. A remove link somewhere
