Support Servlet 3.0 configuration

I really can't figure how to work with this ace wrapper without the web.xml.
The code has no java-doc pointing how it loads files or where it searches. I need my own hosted ace modes as well as custom modes.

Solved. Seems like when using this new configuration vaadin routes everything through its servlet. If you need specific files or folders you need to specify the application URL name in the path, not the java class.
The application name is usually the same as the project name, so in my case the path was:
static/ace
And the path that solved was:
/MiniTaleVerse/static/ace

Seems like only a few files are allowed doing this. The problem persists. Sometimes the files are blocked by the servlet again. I could only load the java mode and cound't load any themes.
