Insufficient Funds Error When Publishing

[guytp]

When trying to post a video with insufficient credits for bid the below error appears. There are three issues with this error:

1. It is not user friendly
2. The check doesn't come back until a long time after hitting publish (I'm guessing the whole upload happens first which for a multi-GB file is a big waste of time)
3. Popup error window cannot be closed whole process must be killed (see Error when publishing with a bid of 0 #23)

Daemon: 0.9.1

@kauffj: Presumably the right way to handle this is to subscribe to the balance and check if the user has enough credits when validating the form. Then if the publish call fails because of insufficient funds (because of a last minute balance change or whatever), we show some kind of modal or notice. I can handle this but it should be done on the redux branch, of course.

Error #3 is fixed already (error dialogs don't get stuck open anymore).
