PSH Downloader

Whacked together this module after being inspired by http://www.pentestgeek.com/2013/07/19/invoke-shellcode/

Generates a psh payload and serves it up via HTTP. Gives you the command line to run on local machine. 

Handy if you don't have web access as per the blog, or working in a test environment etc. Also its somewhere I can goto when I forget the one liner...
