Remove Java dependency from main executable

[shehi]

Hi @zoltan-dulac ,

Checking some forks made from this package, I noticed @raldred has made some significant improvements to the codebase at https://github.com/raldred/css3FontConverter. Could you please view his 3 additional commits in his fork and bring them in, to this original package?

Beware my changes are 3 years old and Mac OSX specific

@zoltan-dulac , can you look at this one please? :)

Hello.

I am more than willing to look into @raldred's changes (as well as the others). His changes are OSX specific and it will probably require a refactor to make sure everything works with other platforms.

I'll update this issue when I have looked into this. Thanks for the reminder. :-)

@shehi : I have not added the changes requested since they are pretty specific to OSX (and since the code has a lot more features since his changes were made).

If you would like to add the OSX dfont support, I suggest extracting the font files from the dfont archive using fondu (which is what his fork uses). fondu can be installed using homebrew or macports, but if you want to compile yourself, I have set up a clone of the original repo (with some changes that will allow it compile under Cygwin for Windows) at:

@zoltan-dulac , can we at least drop Java dependency from the main .sh file please? I have to install that huge platform (JVM) in my Docker because of this line: https://github.com/zoltan-dulac/css3FontConverter/blob/master/convertFonts.sh#L478 Please let's get rid of java check there - we don't really need it, do we? Should I send in a PR for this?
