Update vdexpcsort.user.js to v1.13

Additional search overlay to search by generation and sprite. 
Note: Sprite drop down is generated by a users PC box, a new sprite added to the PC via party refresh will not add it's sprite to this drop down list. Page must be reloaded.
Note: Search terms do not work in conjunction with each other.
Most emoji natures are now searchable, please report any that don't work.
Note: Most Kaomoji do not work. Due to the way greasemonkey for Firefox handles Unicode characters it became quite tedious to search up the Unicode and html representations.
