Backend.fillobj sets a field to NotAvailable if it's not complete.
Always returning False in __iscomplete__ prevents the field from ever
working with fillobj.

Since the StreamInfo is volatile, it's not just the StreamInfo's fields
which should be reloaded with fillobj, it should rather be the whole
StreamInfo object (or its container, e.g. Radio).

object.__new__ only takes one argument: the class to construct.
It accepts more arguments only if __init__ is not overloaded, but it
is overloaded in Abstract*'s parent classes, so don't pass more args.

In Python 2, it was just deprecated, in Python 3, it doesn't work.

The certificate changed and NSS doesn't always seem to accept it, force
it.

A previous patch on regular bred website added "coming" argument to
get_history, which didn't exist, so add it.

When using dir() to find URL fields, we also checked @properties, which
can access other fields that are not defined yet.
Exclude them since they probably won't be URLs anyway.

those are now on the card account

The weboob arg should now be passed as a kwarg, this avoids passing
multiple times the weboob as positional argument in case of multiple
AbstractBrowser.

Creating a new type on-the-fly prevents from using isinstance, super and
more.
We can get rid of this by changing the class hierarchy dynamically.

Also, the modules should now pass the Ouiboube instance as a
keyword-argument to the Browser, so the arguments do not have to be
modified between __new__ and __init__.

The use of metaclass is not required for constructing the dict of URLs.

Plus, it prevents changing the class hierarchy at runtime, which could
be an improvement for AbstractBrowser.

The "index" of the card can only be found in an history page, and same
for the balance.

For the summary transactions, we used to search them in the checking
account and dispatch to the card account, but with multiple cards, it
doesn't fit, so we generate a transaction directly.

Coming transactions have a random id (uuid), so the id should not be
parsed. And they should be separated from history.
