Add a simple field to collect info re: projects

[chadwhitacre]

One notch better than a note to email us. I think this is important to our pitch to companies, per gratipay/inside.gratipay.com#987 (comment).

[chadwhitacre]

Ping @JessaWitzel @mattbk @dmk246 @rohitpaulk et al. for review!

[chadwhitacre]

I have an email ready to send to Yahoo once this is deployed.

[mattbk]

Eep! Mind looking over your info for us?

None of the fields is highlighted...

I'm getting this error irregularly.

[mattbk]

I get that error for all values above $1999. I think this is reason for error above.

Also can't enter decimals, even .00.

[mattbk]

I get that error for all values above $1999.

Same for master.

[mattbk]

Just testing? Other than that it works for me and things show up in db.

gratipay.com/gratipay/card_charger.py

Line 64 in aec5008

- amount >= 2000 returns a failure result

[chadwhitacre]

Yeah if you wire up a Braintree sandbox and turn the form on, then the CC form fields should highlight red when the amount is 2000+.

[chadwhitacre]

Actually, I maybe lied ...

[chadwhitacre]

Alright, I see what you mean about the bad dollar amounts which simulate card charging problems not showing up with an error message in the UI. I don't think this PR introduces that problem though so can we reticket and proceed here?

[mattbk]

Not a problem for me.
