Add a filter by handedness

[esmlb_rop_PSN]

One of the most useful functions of Daddyleagues is the ability to filter players by handedness, but I don't see why it can't be added to the market since it's already a feature in the "my squad" menu.

Another useful filter would be searching for pitchers with a specific pitch, for example filtering for "slurve" would bring up all pitchers with that pitch in their repertoire.
