EtherPAD Duo Login

I've run it through retab. Msfpro loads the module fine. msftidy seems broken though. Gives this on run:
msftidy.rb:444: undefined (?...) sequence: /(?<!\.)datastore\[["'][^"']+["']\]\s*=(?![=~>])/

BR
Rename ehterpadduo_login to ehterpadduo_login.rb
Rename ehterpadduo_login.rb to etherpadduo_login.rb
msftidy done
Adding module description

This module scans for EtherPAD Duo login portal, and performs a login brute force attack to identify valid credentials.
Minor code cleanup
change module filename
