Make @subscribe and @register accept options

[deceze]

The @subscribe and @register decorators should accept the same options as the corresponding methods in ApplicationSession, e.g.:

@register('foo', RegisterOptions(details_arg='bar', discloseCaller=True))
def baz(bar):
  ..

Perhaps even:

@register('foo', details_arg='bar', discloseCaller=True)

This would make code which relies on RegisterOptions/SubscribeOptions much more readable, since it keeps the annotations inline instead of requiring a fallback to onJoin callbacks.

Although not nearly as general as the above, it's possible to set the options for all @register methods in your class by passing an options= arg like self.register(self, options=...) when you do the registration.

Something like the above would be good, though.
