Partial class name completion patch

[nkkarthik]

I have modified the code to auto-complete a partial classname, without needing the package name (makes it very easy to find/enter class when you forget the package name or even the exact class name). I found it useful in my personal work, so thought could help others too.

It behaves as below:

user> (complete.core/completions "JFr")
("javax.swing.JFrame")

user> (complete.core/completions "Rob")
("java.awt.Robot" "java.awt.peer.RobotPeer")

Wildcard '*' is supported and can be used as below:

user> (complete.core/completions "Win*Ad")
("java.awt.event.WindowAdapter")

user> (complete.core/completions "Mou*Li")
("java.awt.event.MouseListener" "java.awt.event.MouseMotionListener"
"java.awt.event.MouseWheelListener" "javax.swing.event.MouseInputListener")

user> (complete.core/completions "Mou*In*L")
("javax.swing.event.MouseInputListener")

Uploaded patch here: https://gist.github.com/3117608

Changes:

1. Use class names as potential-completions when there is a capital letter in the prefix (a curde assumption, I have to agree, that clojure vars may not have capitals).
2. Instead of startsWith, use regular expression match to support wildcard too (see re-match).
3. Some tests are updated.

Let me know what you guys think about it.

Thank you
