Added Call and removed loading error

Call runs a program and waits for it to close before continuing

If you run QuickTerm without Args it now skips config check
Removed .NET 4

This version was not needed because everything in the .NET 4 version was
already in the .NET 2 version. If, for some reason, you need .NET 4 then
compile it with that target framework.
Simple bug fixes
Made Visual Studios compile into the progs folder
