ConsoleRunner: Fix an UnsupportedOperationException in main

Hello.  I am trying to use jline2 with JDB so that the up arrow key will work properly when I am entering commands for JDB.
This was apparently possible with older versions of jline with the procedure is described here: http://stackoverflow.com/questions/13877802/text-navigation-in-jdb-not-working-in-bash/13877842#13877842

However, there is at least one problem in the ConsoleRunner class that makes this currently impossible.  To recreate the problem, I cloned jline2 to my Arch Linux machine, ran `mvn install`, and then I ran this command:

```
$ java -classpath target/jline-2.12-SNAPSHOT.jar jline.console.internal.ConsoleRunner abc
Exception in thread "main" java.lang.UnsupportedOperationException
        at java.util.AbstractList.remove(AbstractList.java:161)
        at jline.console.internal.ConsoleRunner.main(ConsoleRunner.java:48)
```

The problem is that ConsoleRunner is trying to modify a list of strings that was created using `Arrays.asList`.  This is not possible, as explained here:
http://stackoverflow.com/questions/7885573/remove-on-list-created-by-arrays-aslist-throws-unsupportedexception

After applying the fix presented in this pull request, the same command gets past the point where it was failing and gives a better error:

```
$ java -classpath target/jline-2.12-SNAPSHOT.jar jline.console.internal.ConsoleRunner abc
Exception in thread "main" java.lang.ClassNotFoundException: abc

        at jline.console.internal.ConsoleRunner.main(ConsoleRunner.java:75)

```

I don't understand how ConsoleRunner ever worked.  Perhaps it was developed on a version of Java that behaves differently from the one I am using?  I am using the following JDK packages in Arch Linux:

```
$ pacman -Q | grep jdk
jdk7-openjdk 7.u51_2.4.4-1
jre7-openjdk 7.u51_2.4.4-1
jre7-openjdk-headless 7.u51_2.4.4-1
```

My editors (both emacs and nano) also added a newline to the end of the file.  Sorry, but I didn't think it was worthwhile to figure out how to avoid that.
