Complete Rewrite to C#

[mjishnu]

I am planning on rewriting alt app installer to a C# (windows app sdk) app. The reason for doing this is due to the following advantages:

• Improved performance
• Reduced resource usage
• Better API Support for windows-based tasks
• More native support for arm-based devices
• Easy to package and distribute

In the re-write I am planning on making alt app installer more like a store, currently we open a browser window and select the app instead I am planning on doing this via API similar to how Microsoft store does it. and introduce features like updates for installed apps etc. I am not sure how long it will take or how much of my goals are feasible. So, I won't be doing any major changes to alt app installer in the mean time but if you spot some bug feel free to open a issue, for new features if you are willing to implement them be sure to open a PR.

As mentioned above the new re-write will be much more than an installer so I am thinking of giving it a new name so if you have any name in mind share it here also feel free to give suggestion regarding new features you think will be useful.
