NAT Logging appears to be broken at the moment in both the rolling release and 1.4. This is a good time to add some additional `show log` options.
Fixed commands:
`show log nat`
Added commands:
`show log nat source`
`show log nat source rule <ruleNume>`
`show log nat destination`
`show log nat destination` rule <ruleNum>`
`show log nat static`
`show log nat static rule <ruleNum>`
