AAL/Python: handle adapter exceptions from output actions

adapter_exception_handler was called if an exception occured while
polling outputs, that is, executing adapter blocks of output
actions. The problem is now fixed, and the return value of
adapter_exception_handler is handled similarly to input action case
(see doc/aal_python.txt).
AAL/Python: adapter_exception_handler can silence output

adapter_exception_handler is allowed to return False if handling an
exception from the adapter of an output action. (It means that the
action was not observed.)
