Change delimiter for ZED email scripts

Browse Source 
When the ZED_EMAIL_INTERVAL_SECS="3600" option is set in zed.rc
configuration file then notification emails should be rate limited.

Rate limiting is accomplished by maintaining a colon delimited state
file which includes the device name.  Unfortunately there are valid
device names which include a colon and therefore prevent the rate
limiting for working properly.  For this reason the delimiter has
been changed to a semi-colon.
