Add windows batch compatibility

[VincentBlondeau]

This PR aims to add a support for batch (native windows console) for ZeroConf.
The files are still the same but the few lines at the beginning allow to choose between Win and Unix.

Only images >= Pharo7 can be downloaded properly. (I do not plan to implement it for lower versions).

Testing can be done locally with this piece of code:

AbstractZeroConfBashScript compile: 'baseUrl
	^ ''http://localhost:4567/'' asZnUrl'.
ZeroConfCommandLineHandler generateInDirectory: 'GeneratedFiles' asFileReference 
.
server := ZnServer on: 4567.
(staticFileServerDelegate := ZnStaticFileServerDelegate new)
	prefixFromString: ''; 
	directory: 'GeneratedFiles' asFileReference ;
	mimeTypeExpirations: ZnStaticFileServerDelegate defaultMimeTypeExpirations. 
server delegate: staticFileServerDelegate.
server start.

Developed and tested for Windows 10 x64 and Firefox.

Nice and important initiative, I hope you manage to avoid breaking things ..

[VincentBlondeau]

Thanks @svenvc !
I cannot try on all the unix's so if you can test locally it will be great! (and the tests are not running on windows too.....)

[VincentBlondeau]

I also made a bit of refactoring to use the fileBaseUrl instead of hardcoded values

This PR has not been integrated and is now in conflict with the latest changes... Is there anything blocking this?

[guillep]

I'll take a look!!

Is it possible to have this PR fixed for Pharo 10?
