USAGE:
Add following structure to your Django settings file:
XMLRPC_TEMPLATE = "xmlrpc.html"
XMLRPC_METHODS = {
    'xmlrpc1': (
        ('module.xmlrpc.method', 'exported_name'),
        ('module.xmlrpc.module', 'module_prefix'),
    ),
    'xmlrpc2': (
        ...
    ),
}

<key>_handler method is created for each key in XMLRPC_METHODS
(xmlrpc1_handler and xmlrpc2_handler in this case).

It is encouraged to use __all__ when exporting whole module.

All double underscores in method names will be replaced with dots:
def task__create(request, ...): will be registered as task.create(...)
