Job#setttl should return self?

[ansman]

Seems like most non result methods returns self (I'm assuming for chaining purposes) but setttl does not:

def setttl(self, value):
    self.post("control", action="setttl", ttl=value)`

[blovering]

Yes, these "actions" return self in order to enable a "fluent" style of coding (aka chaining) and this one should also return self.

Fixed in the develop branch.
