All Our Ideas member

We'll now return JSON response for 500 errors if the request is expecting JS. This allows our JS to inspect the error message and display a customized error message to the user based on the error. We know have 4 different error message (previously just one) for Ajax errors that happen in voting, skipping, flagging, or adding an idea.

@lukebaker lukebaker for all exceptions return proper response type
For JS requests, return JSON and for HTML requests return HTML

@lukebaker lukebaker improve error messages after votes, skips, etc.
For any Ajax action that has an error we will parse the JSON to look for the
error name. Right now, we're looking only for CantFindSessionFromCookies since
we already had a message for that. If the user gets an error that we're not
explicitly looking for then it'll display a generic error message with that
error name. We also have error messages for timeouts of requests or requests
that got cancelled.
