fix #45 set command quoted

[Timsonrobl]

In set command parameter value read from %~p* parameter extension needed to be quoted to avoid special characters (like &)from path breaking command.
Current implementation:

SET dp0=%~dp0 

evaluates to

SET dp0=D:\CODE\dir-name-with & amp\vite-project\node_modules\.bin\ 

passing all characters after & as shell command (and failing):

"amp\vite-project\node_modules\.bin\" is not recognized as an internal or external command, operable program or batch file. 

Quoting set command parameters seems to fix this issue completely.

It seems tests still fail:
