Description of problem:
Can't select all errata to be applied from the Content>Errata menu.

Version-Release number of selected component (if applicable):
6.12

How reproducible:
100%

Steps to Reproduce:
1.Mouse over "content".
2.Click errata.
3.Click checkbox for all errata.

Actual results:
20 errata will be selected. You can change the pager to show 100 errata but if you have more than that, you'll have to select all errata manually. I'm aware that a better method for applying errata is through Collections however this is just not a great experience for the user.

Expected results:
Select all errata.

Additional info:
If you apply errata through collections, there is an option to select all errata. Can we make that available as well as an option to schedule the application of all errata like through collections?
