displayshow/coming ep tweak

**displayshow**
* Only show the latest season by default, click button to load the remaining seasons.

  > Should help with slow page loads (still not a true fix but works for now).

* Specify some widths to reduce how many calculations the browser needs to do (less repaint/re-flows)

* Enable manual search of specials once again.. 

* Added ability to filter **SNATCHED**

**coming episodes**
* Allow sorting of **Next Ep** data, minor cleanup
