Patch for string encoding issues with `msgpack`

Fixes an issue that causes exploits to fail if the PAYLOAD option is the last option to get marshalled in an MSFRPC dictionary. The patch adjusts the string's encoding to match the internal default encoding used by Ruby. Hence, making `fetch()` succeed.
Remove module version display

Since modules no longer use the 'Version' key, there's no point to
collect and show them. It's all 0 anyway.

Get rid of version() use
Add module to brute force the Cisco IronPort application
cisco_ironport_enum module

This module scans for Cisco Ironport SMA, WSA and ESA web login portals, finds AsyncOS version and performs login brute force to identify valid credentials.
new revision - cisco_ironport_enum

Added code to check successful conn first, so now if there is no connectivity on target port, script aborts run.
New check to ensure 'set-cookie' is set by the app as expected, before any further fingerprinting & b-f starts.
If the app is not Ironport, 'set-cookie' will not be set & remains null, and so script aborts run.
De-registered 'TARGETURI.'
Registered 'username' and 'password' with default value.
Changed some run messages.
And lastly, changed the csrf key piece cos I miss a cold beer right now.
