Added Get-Webconfig Password Dump Function 

**Get-Webconfig Summary**

This script will identify all of the web.config files on the system and recover the connection strings used to support authentication to backend databases.  If needed, the script will also decrypt the connection strings on the fly.  The output supports the pipeline which can be used to convert all of the results into a pretty table by piping to format-table.  

The script has been working great on IIS servers during recent pentests, but let me know if you have any questions / fixes .

Thanks,

Scott
