Work towards #4357 #4355 . Also some miscellanious tweaks:

• Default sort order is now random instead of most editions. This random changes every hour, so different books are show regularly.
• Fix: When sorting in "Shelf order", only consider best classification number
  • This makes jumpTo possible
  • This also fixes a case where sorting by "Shelf order" caused a bunch of unrelated books to appear first
  • This does mean that when in shelf order, books that are shelved at multiple classification number will only appear at one
• Fix: Searching for queries like lcc:E--*
• ClassSlider now has 9 fewer html elements; yielding ~900 fiewer elements in the total UI
• Small perf tweaks setting things to contain: strict where possible
• Alpha: ?jumpTo parameter:
  • eg: http://testing.openlibrary.org/explore?jumpTo=lcc:RB-0158.67
  • eg: http://testing.openlibrary.org/explore?jumpTo=ddc:028.5
  • Known issues:
    • lcc parsing isn't quite right; sometimes needs "normalized" LCC, sometimes fine without it
    • LCC is slower; should show loading indicator
    • Need a better visual indicator of where book is
    • Need a way to change filters, but still remember jumpTo position
