Make use of new jshint options * Restricting "camelcase": No changes, we were passing all of these already * Explicitly unrestricting "forin" and "plusplus" These are off by default in node-jshint, but some distro of jshint and editors that use their own wrapper around jshint instead of node-jshint (Eclipse?) may have different defaults. Therefor setting them to false explicitly. This also serves as a reminder for the future so we'll always know we don't pass that, in case we would want to change that. * Fix order ("quotemark" before "regexp") * Restricting "unused" We're not passing all of this, which is why I've set it to false for now. But I did put it in .jshintrc as placeholder. I've fixed most of them, there's some left where there is no clean solution. * While at it fix a few issues: - Unused variables ($target, $window) - Bad practices (using jQuery context for find instead of creation) - Redundant /*global */ comments - Parameters that are not used and don't have documentation either - Lines longer than 100 chars @ 4 spaces/tab * Note: - ve.ce.Surface.prototype.onChange takes two arguments but never uses the former. And even the second one can be null/undefined. Aside from that, the .change() function emits another event for the transaction already. Looks like this should be refactored a bit, two more separated events probably or one that is actually used better. - Also cleaned up a lot of comments, some of which were missing, others were incorrect - Reworked the contentChange event so we are no longer using the word new as an object key; expanded a complex object into multiple arguments being passed through the event to make it easier to work with and document Change-Id: I8490815a508c6c379d5f9a743bb4aefd14576aa6
