REPL almost unusable

[Daniel Finnie]

The REPL used in Lighting Console should steal some features from IRB including:
- command history
- tab completion
- color?
- hotkeys?

The Inline gem can do a lot of this:
http://inline.rubyforge.org/

Also, the junk that prints after most commands is worthless and takes up too much room. Get rid of it.

Great strides have occurred and been pushed to the console branch.

Still to do:
- Fancy features like history at the command line.
- console.rb getting very messy, should refactor before it gets too deep.
- need to move things like dmx refresh into console.rb
- need to figure out a solution to these requires.
- lighting board command line needs to do something, not just figure out what channels it will work on.

The gem that I used to do this, Inline, really sucked memory and didn't work very well.

Next plan is readline -- copy IRB.
