Add a way to display login/register errors

[mjohnson9]

I'm not sure how we should go about this, but I can think of two ways:

1. Use session flashes
2. Use a query parameter

I like option #1. My only concern is the gorilla/sessions flashes don't provide a way to set the status fo a message. E.g. 'error', 'success', ect. That may not be an issue, though.

I've begun work on a starter app (gaego/starter). I think it will be easier to reason about some of these things with actual code.

Here's what I use in one of my production apps for flashes: https://gist.github.com/1fa38992813ca9b63c2c

I just insert those directly using AddFlash.

Nice! Do you think this could be incorporated into the session package?

[mjohnson9]

Certainly, that would be a great place to put it. Would you like to add it?

Consider it released it under the Public Domain (or zlib license where Public Domain isn't recognized.) Those should both be compatible with the BSD license.

I won't be able to work on code for the next day or so. I'm reformatting.

Thank you :) I'll look into incorporating it in the next few days.
