Request to pull added command line interface and Ant build file

[hflicka]

Hello Daniel Grunwald!

I currently work as student assistant for Dr. Klaus-Hendrik Wolf. In this context, I was asked to add some features to arden2bytecode, one of them being an easy-to-use interface. I chose to add a command-line interface in the first. I used the included JewelCLI lib for parsing. Also, I added the option to use Ant for building the program. Further I changed the Eclipse project file to use an Ant builder in conjunction with the build.xml to fire up SableCC.

So far for the major changes. If any questions, feel free to ask. Not all command line options are working yet, but I plan to add the missing functionality.

Regards, Hannes
