[users at bb.net] 0.9.7: ShellCommend log observer

[Pierre Tardy]

Hi Drago,

There is no supported way to add Logobserver outside of subclassing.

This is because steps are actually re-instanciated at each build, so the
step objects that you manipulate in master.cfg are actually not used.
Buildbot only keep their class and the list of parameters used to
instanciate them.
