Added a simple method to integrate shell commands.
Add support for XML doc to the describe command.
Additionally means to list namespaces and classes.
Adds some colors to booish.
There is still an error to be fixed. One currently cannot end blocks.
I thought about doing more but I thing that I will stop here (except that naughty error mentioned above).
Adopted assembly version to those of the original Boo distribution.
Now the console again can apparently indent and deindent properly.
