[tor-commits] [bridgedb/master] Change PluggableTransport.methodname to be a @property.

commit 70019ff8944cd29de272d34f432247b055045006
Author: Isis Lovecruft <isis@xxxxxxxxxxxxxx>

    Change PluggableTransport.methodname to be a @property.
    
    This ensures that it's always lowercased when set, removing the need for
    so many lower() calls.
