Subject: [PATCH] Connect wallet and fill in address during signup

In case there's a wallet available, ask the user to connect it and fill
in their account address in the form field.

Also, check the status code when submitting it to the back-end and show
an error message instead of the success/completion page in case the
contributor could not be created.
