corrected grammar
one step further towards working reloptparser (missing clauses are the
last thing to fix)
intermediate layer between messagebuffer and parser for clean separation
of functionality (Backend.java)
applied listener-pattern to backend for support of exchangeable
representations
adding relopts on the fly to the gui now works almost properly
(duplicate layers in some cases)
moved some classes to more intuitive packages
removed old indent-insensitive parser
