New little features in Descent

[Ary Borenszweig]

Hi!

I ported some code and features from Eclipse 3.4 and 3.5 to Descent, 
which are already present in the Java Development Toolkit for Eclipse 
(JDT). These features are:

- The popup is nicer when hovering a symbol, showing it's icon and 
allowing to open the ddoc view or the declaration.
- The popup also shows compile-time values of constant variables and 
enum members when available.
- The completion proposal list is nicer, showing the declaring type or 
module in grey (it's cleaner to the eyes). Also fields and methods are 
separated by ":" from their type.
- When hovering a method with ctrl hold, two options appear: "Open 
Declaration" and "Open Implementation". The first one just jumps to the 
method declaration. The second one opens a popup showing the classes or 
interfaces that implement that method, allowing you to quickly navigate 
to one of them. This is very useful when programming to interfaces.

Here's a video showing all of these things:

Enjoy!
