Bug 10725: Add filters on the pending orders table

Since the parcel.pl script get *all* pending orders, there is no reason
not to display all of them.

Like that, DataTable manages pagination and sorting correctly (on all
data).
This patch adds filters on the table header (using columnFilter).

Test plan:
Try filters on the left of the screen and filters on the table header.

Passes all tests and QA script.
Searching and sorting the table works correctly.
Larger result sets are a performance problem on this page,
I have filed bug 10595 for that.
