BillQuick Web Suite txtID SQL Injection

This Metasploit module exploits a SQL injection vulnerability in BillQUick Web Suite prior to version 22.0.9.1. The application is .net based, and the database is required to be MSSQL. Luckily the website gives error based SQLi messages, so it is trivial to pull data from the database. However the webapp uses an unknown password security algorithm. This vulnerability does not seem to support stacked queries. This Metasploit module pulls the database name, banner, user, hostname, and the SecurityTable (user table).
