Merge pull request #13 from rpunt/master

Added Police/Fire scanner codes
Added current keyboard shortcuts to emmet cheatsheet
Emmet kbd -> code tags, style tweak
Cheaters update, persistent options, quick search

Contrast settings and active sheet are now stored across sessions.

Typing "g" will open an input for quick, fuzzy jumping between sheets, and if the query starts with "?" it will be treated as a search. "?so query" searches Stack Overflow, "?go" Google, "?gh" Github and anything else, DuckDuckGo (bang searches work).
