Stem's convenience method for saving configuration using SAVECONF
I'm implementing the convenience method for saving Tor's current configuration using SAVECONF.
My implementation is here (this commit). I've based it off my setconf branch because it's using the SingleLineResponse I implemented in it, so this will have to merged after that (which is based on the getconf parsing, because the tests need it). I wish had done this seperately, but, shrug.
I also fixed a few things in the documentation which reappeared after a bad rebase to master. such as...
- :var str code: The error code returned by Tor (if applicable)
- :var str message: The error message returned by Tor (if applicable) or a human
+ :var str code: The error code returned by Tor
+ :var str message: The error message returned by Tor or a human
