added busy mode and test

Browse Source 
a command can now return SHELLMATTA_BUSY
This will be passed back to the caller of processData
afterwards the instance has to be called with the same parameters
The shellmatta will then just call the busy command until it finishes
as soon as the command returns != SHELLMATTA_BUSY the instance will continue processing the rest of the input data
