New cxs v3.05

Changes:

Added /etc, /sys and /proc to directories requiring –force to be used when scanning
Added additional checks that any specified quarantine directory is valid
Added new option –ctime [hours]. If you run regular full system scans then you can use –ctime [hours] to only scan files changed in the intervening hours. This can speed up scan times dramatically
Apply hfile:, hdir: and hsym: ignores to FTP upload scanning
