Add filter/rearrange rows capability to table

[avoidthehack]

To make comparing specific browsers easier, add a method to either 1) filter rows (likely less efficient due to number of records in the table, the filter list would be long as it would include every browser listed in the table) or 2) rearrange rows according to user discretion.

DataTables appears to have a function for rearranging rows, so this may be easy (lol) to implement.
