Allow both cleanmethod values to be specified at the same time 

No reason to disallow this- it allows keeping even more packages around in
the cache. Test cases included for this case and to ensure the default
behavior is preserved.

*CleanMethod =* KeepInstalled | KeepCurrent::
*CleanMethod =* KeepInstalled &| KeepCurrent::
If set to `KeepInstalled` (the default), the '-Sc' operation will clean
packages that are no longer installed (not present in the local database).
If set to `KeepCurrent`, '-Sc' will clean outdated packages (not present in
any sync database).
The second behavior is useful when the package cache is shared among
multiple machines, where the local databases are usually different, but the
sync databases in use could be the same.
sync databases in use could be the same. If both values are specified,
packages are only cleaned if not installed locally and not present in any
known sync database.

Log action messages through syslog(). This will insert log entries into
