Update the CONFLICTS definitions of ports in the following categories:
- accessibility
- archivers
- audio
- benchmarks
- biology
- cad
- chinese
- comms
- converters
An attempt has been made to use generic conflicts patterns that do not
have to be updated whenever a new version of a conflicting port is
added to the ports system.
There is a misunderstanding that the port being built/installed has to
be omitted from the conflicts pattern. This is not true - the port
being built is implicitly non-conflicting due to logic in bsd.port.mk.
