Add module-info.java

So that it will be a dedicated module instead of an automatic one.

@KleaTech what module system are you referring to ? Jar packaging or something else like OSGI ?

[KleaTech]

I'm of course referring to the Java module system

However I tried to do it myself and it is not possible as long as you use Xerces. Neko HTML also had to be replaced, but it was relatively easy. I don't remember what I used instead.

Pdf2Dom still targets to Java 8 so the modularization of the library could cause problems. However, I added the Automatic-Module-Name: net.sf.cssbox.pdf2dom declaration to the manifest so that the automatic module name should be stable now. Does it solve your problem?

I have also moved the CSSBox bindings to a separate projects so now the dependencies so now it should not depend on xerces and NekoHTML anymore. (see the recent commits in master)

The stable module name is nice to have. It's best to add it to every project that targets java 8 or earlier. However for what I tried to do, it's not enough. I tried to pack my own JRE with jlink, but to use it all dependencies in the dependency hierarchy must be a Java module, no automatic module can be used anywhere. As I said earlier this can be done except for Xerces.
Removing to CSSBox dependency may solve this problem, I will check it out.
