Support for Java library keyword completion

[tiluoma]

First of all thank you for awesome plugin :)

I have a feature request: Auto completion for keywords implemented with Java and included in test project as dependecy. It would be awesome if auto-completion would work just by including a new test library..

..this is solved on some plugins for other IDEs: list of keywords in .index file (as used in Eclipse robot plugin) or getting keywords from a Java spec file (RIDE development environment uses this approach https://github.com/robotframework/RIDE/wiki/Keyword-Completion#using-library-specs)

Hi @tiluoma,

the java direct support is not planned at the moment, but the usage of the libdoc xml format to help the plugin keyword detection is actually a very nice suggestion.

Thanks a lot!
