added command-line option -[no]dummywrite to create snaphots of each frame without writing them to a file [Oliver Stöneberg]

Browse Source 
this is a dummy implementation of -aviwrite/-mngwrite and is used in
testruns to detect e.g. palette issues. the dummy implementation greatly
speed up testrun since it avoids the snapshot to file format conversions
as well as the I/O operations
