Introduced "all attacks" switch in GUI, and a bugfix.

Passing the '--all-attacks' switch to the backend was not working. The reason
was the hack to get Vista working hardcoded cutting to the last attack found.

In the long term, this needs to be cleaned up, and cutting should be moved back
nicely to the Scyther C code where it used to work. Once done, switches.useAttackBuffer
can be set back to true.

BUGFIX: When cutting attacks/patterns, counts are no longer exact.
