Set version number to 1.2 (dev)
Use -f option to rm for uninstall target

* In order to avoid errors when uninstalling caused by files not
  having been installed.
Remove cycling key maps (e.e. use o to cycle between oscs
Removed underline from certain parameter box names

* Namely those who now are not reached by cycling.
Fix erroneous step range for arp tempo parameter

* Using cursor to scroll would work, but the value sent to the Blofeld would
  be wrong. Using scroll/inc/dec would result in a max value of 127, and
  again the value sent to the Blofeld would be incorret.
* Seems to be something odd still, sometimes the value is off by one
  parameter (not ui) step value. Could be a rounding error. Still better
  than it was before this commit.
