Default colors are fixed as Java default.

The colors are so fancy. 
I thought the default was inherited from the default editor. However, I have to fix the color in the xml files.
Now, everything looks as same as Java default colors.

The reason I talked about bnf design is meant for handling <<eof>> end of file as well. Personally, I tried and checked how to use <<eof>> well. Still there is no luck for me. You might see that "Method call" in in Java colors setting page. I like this feature when I am coding. But, it is really personal perspective. If you don't like it, I will remove it.
