Minor change to read me
add context handler for sentry dsn
add raven and some global variables to BB
add raven.js for development and config
add git commit to raven logger
bump selenium version for travis
fix minify issue with regex items
only load raven when dsn has been set - having it in debug isn't necessary
get sentry/raven settings from the secret dsn and strip out private key when making it available in the templates
- allow 'rel' to be used in goto links as tinymce can't handle data-target
- added tinymce_bb editor which extends tinymce_advanced so we can customise valid elements in editor
move current user fetch + language setup into ember initializer
scroll to top when entering signup route
*without* the key
