Adding framework to allow MyGet Build

Adding the necessary scripts etc to allow compilation both locally, and via MyGet Build Services.  This will allow pre release of package on a public MyGet Feed, and once tested and verified, package can be pushed to the upstream Chocolatey Repository.

Some more information on this...

I have created a new feed on http://www.myget.org/ with the name of shanselman, you can see it here:

https://www.myget.org/F/shanselman/

Assuming that you want to go ahead with this addition to the Wifi Manager, if you create a MyGet User Account, I will transfer ownership of the feed over to you.

With this feed in place, I am then using the MyGet Build Services, as documented here:

http://docs.myget.org/docs/reference/build-services

To pull the source code from my choco-myget branch, and then the MyGet Build Engine (code named Wonka) takes over, to build the entire solution, and then package the exe into the chocolatey package.  In addition, assuming that the build is successful, will automatically add the nupkg file onto the MyGet Feed.  As a result, you can then do:

cinst wifi-manager -pre -source https://www.myget.org/F/shanselman/

(Go ahead and try this.  You should get a new Chocolatey package installed, with the latest version)

MyGet Build Services automatically takes care of updating the AssemblyInfo.cs files within the solution, based on a version number format that you specify within the configuraiton.  For now, I have used 0.2,0-pre{0}, where {0} is replaced with a build counter that is maintained within MyGet.

This obviously allows testing/verification of the pre-release package.  Then, when you are happy with it, you can push to an upstream package repository (in this case chocolatey), and the MyGet System will strip off the pre-release flag, and push just the published version to Chocolatey.org.

Hold on, how much is all this going to cost you?  This is the best part, it won't cost you anything :-)

If you want to go ahead with this, the following steps will need to be taken:

1. Create a MyGet Account and I will transfer ownership of it to you
2. Accept Pull Request
3. Update MyGet Build Definition to pull from master branch of your GitHub repo
4. Add your Chocolatey API Key to the Upstream Package Source within MyGet
5. Add the MyGet HTTP Post Hook Url to your GitHub account, so that any checkin's to the master branch results in a new build (this is documented here http://docs.myget.org/docs/how-to/auto-trigger-a-myget-build-using-an-http-post-hook-url)

I think that is it :-)  If you have any questions before going ahead with this, just give me a shout.

It looks very much like the Wifi manager is evolving, and you may actually need to Chocolotey packages, namely wifi-manager.app (the full UI version) and wifi-manager.tool (which is just the exe), but this can be easily added to the psake script that I have added to the build.
