Add Eventlog Analzyer exploit for CVE-2014-6038/6039

This adds an exploit for two zero day vulnerabilities in ManageEngine EventLog Analyzer. 
Versions 7 to 9.9 are vulnerable to a SQL database information disclosure (allowing you to dump any table from the database) and an information disclosure vulnerability that allows extracting the password for any managed Windows and AS/400 hosts.

This module has been thoroughly tested on Windows and Linux versions of EventLog Analyzer.
Since your module is gathering credentials, it should report them using the ```metasploit-credential``` way. https://github.com/rapid7/metasploit-framework/wiki/Creating-Metasploit-Framework-LoginScanners

Even when this module isn't a LoginScanner, worths to report the credentials in the same way. There are several examples of auxiliary modules gathering credentials and reporting them in the ```metasploit-credential``` way, even they aren't Scanners, for example: modules/auxiliary/server/capture/imap.rb
