Changed the Jline Version from 0.9 to 2.11
Ported to JLine2 and Java 1.6

JLine2 is the actual version of JLine and its package structure
has been changed from Version 1 to 2. Also tiny little changes on
coloring has been done.
Reading passwords from command line is now done by the java 1.6 api,
so the sources needs to be built against Java 1.6
