In the 'PLC developer', a Python file can now be selected as a start
project on the Revolution Pi. This is transferred to the Revolution
Pi via the new XML-RPC function 'set_plcprogram'. This version is
available from 'revpipyload' 0.11.0.
The creation of folders was not clear and a bug could rename wrong
elements, which the user does not select.
Now connections and folders are handled in separat ways and the user can
add a new folder by pressing a button.
