Support Ctrl+Arrow for word jumping

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Open the terminal
2. Write a line of text with multiple words
3. Type Ctrl+<Left-Arrow> to jump back one word

What is the expected output? What do you see instead?

I expect the cursor to jump back one word. Instead it jumps back one character.

What version of the product are you using? On what operating system?

1.0, Eclipse Juno, OpenSUSE Linux 12.1 x86_64.

I guess that neither Ctrl nor Alt keys are handled in ELT for now. On the other 
hand Esc-b and Esc-f (forward-word and backward-word) from readline work just 
fine.

My bad. Other Ctrl key combinations (Ctrl-<AWUE>) work as well.
