Major change with multiple features

* Virtual Directory Support
* section unlock and lock support
* fixed issue with :add on pool provider not running all config
* fixed issue with :config on all providers causing application pool recycles (every chef-client run)
* moved to better method for XML checking of previous settings to detect changes

I apologize for the large pull request but the speed of approvals is taking too long and we have had to write too much code.
This is basically just the way the ternary operator is, it makes for less code but it of course makes things slightly harder to read.  This was a personal decision since this is something that needs to be maintainable even if it is complex.
