Adding the ability to launch from a folder/parent folder with spaces in it.
Added quotes around cmd.exe launch to prevent problems with spaces in the path. Added powershell arguments for default profile script and to not load the windows level profile. Added CMDER_ROOT to powershell arg. Added powershell script and script dump folder, which contains a script definition to mirror cmd's prompt style.
Quotes break the cmd prompt, I don't know why.
