Play now gets a new card on Rate or Skip action

Only asks for and displays a new card. Passes a rating parameter, where
appropriate, but not to the server.
Changed Play UI per Shade's recommendations

If you think the F1 icon on :hover for the help button doesn't
contribute anything, feel free to say so.
Replaced some algorithm engine stubs and added some algorithm functionality
Scores landing page layout, switch button redesigned.
Merge branch 'development' of https://github.com/latreides/SE_Team3 into development
Fixed up display of search results for decks
Redesigned the scores calculation to take in real database values.
Fixed hotkey typo & added hotkey desc. to interface
UI for uploading images in place
UI Improvements & Img Preview added to Edit pg.
Added time element to algorithm and difficulty updating into view - DB MIGRATE
Legend values now display for 0 and deck name updates on scores page.
Added image handling to import/export functions
Added image validation to uploading

This is a fallback for the next development stage of image uploading in
case the ajax post goes poorly and I need a "restore" point.
Valid image submission currently just takes you to a "Success!" page--to
be replaced by ajax call.
Current image preview implementation to be replaced.
Added redirection page for invalid or hacked access decks.
Added image addition to the edit deck page.
Fixed some bugs with deck creation and added the beginings of showing images in deck play.
