Add TShock.Installer to download dotnet runtime

Browse source 
This will include a new ./TShock.Installer executable that will be for users without the dotnet runtime. This program will download the dotnet runtime, extract it, and then run ./TShock.Server for them using the downloaded runtime.

Note: only tested on osx, likely a no-go for linux/windows until more testing occurs.
