Add the ability to filter and sort one to many tables like those that are used for Translation Tables

[mdnoble73]

We currently use jquery.tablesorter which has been updated to allow filtering of input controls:
https://github.com/Mottie/tablesorter
We could use that or we can add pagination, filtering, and sorting to the form itself which would have the advantage of reducing the amount of memory used and which would mean that we no longer need to extend the number of post variables we allow for larger sites.
