change email field length of signin form from 20 to 200

No description provided.

Acked.

I checked the length in model is up to 200, so it is safe to merge this pull request.

However it would be better if the description be more specific.

[ibigbug]

ACK.

Obviously, email lenght > 20 would not sign in correctly.

I've updated in my local repo.

OK

@ibigbug Remember to create a new branch for every pull request.

Why?

In fact, I created a new branch and deleted it after merge it into my own master..

[liuw]

@lepture This is rather a bug fix than a new feature. IMHO there is no need to open a new branch for simple fix like this.

[lepture]

@liuw keep the master branch the same as upstream.

[liuw]

@lepture we should probably discuss the workflow on Python-China? I'm kinda confused how things work now.

@liuw create a topic!
