Title: Make Windows installer PATH alteration optional, add environmental command prompts

The user now has the option of whether to modify their `PATH` or not. It looks like this:

I've also modified the installer to create three batch files, `dmd2vars.bat`, `dmd1vars.bat`, and `dmcvars.bat` along with a Start Menu shortcut to each. These function like the Command Prompt shortcuts that come with Visual Studio or TDM-GCC. It simply sets that `PATH` to include the appropriate bin directory. This is useful for people who work in both D1 and D2 or people who don't want their `PATH` modified systemwide.
