[PD] pixeltango nice feature not tested

[patrick]

hi,

in pixeltango there's a nice feature. if you touch a [commun] object you can 
assign a midi controller to it. i didn't test it, but i think it's there. 
for an example:

1) you touch  rotate_x slider
2) you turn a know on your controller
3) the rotate_x is assign to the last cc
4) you save this routing

it would be great to have this kind of template in memento!
