Add java language support

[lhein]

[apupier]

Several possibilities:

• use own Java parser but how to handle classpath/dependencies?
• provide an extension of jdt.ls
• use a first iteration with searching for files containing org.apache in import package and with from("")/to("") (oh yes ugly but can provide result faster)

Other things to take care:

• for xml, the & are escaped in & will need to provide an option to do it or not Add java language support #6
• declaration of files supported (currently xml file sonly in all clients - maybe something on server side too?)
• other?
