Syntastic doesn't check on :wq when disabled, and toggling
active/passive also toggles check on open/wq. A new variable was added
to prevent autochecking tags, and the README and update script were
updated to reflect this. Disabling the linebreaks is now defaulted to
off (flip it back on if you like it). The update script is a bit more
careful about how it runs when executed from other directories. A bug
preventing the g:disablelinebreaks variable from being possible to
disable has been squashed, and no default is set when it's not enabled.
Added Emmet javascript (rather than just json), and tried to sync up the
webformat list between plugins that enable themselves for those.
