now it should work

this change can save your keys if you have a bad day and enable debug in django.settings

look in my branch (in my fork) for progress. I am not ready with the paydirekt provider, as its refund capabilities are not tested

When I have sandbox access, I can complete the paydirekt backend. Should be the next days.

Afterwards I will make a merge request. (it will be very big, as it contains some features and bugfixes)

I will add the backends later. See my pull requests; I splitted the changes into small pieces.

good idea

I am not sure if this pull request is a good idea. Most people just want two decimal_places and 12 digits.

anyway it is very domain specific (if you want to trade bitcoins or not)

the state is also very unsatisfying for me. I solved all problems but no feedback (may I changed too much). I can do and think about a fork.
