Classify test result tree items more precisely

[GoogleCodeExporter]

Currently, a tree item can be only a success (a green tick is shown) or a fail 
(simbolized by a red cross). The purpose of this task is to extend the types of 
result the item can represent.

There will be 6 types:
-Success (already implemented)
-Fail (already implemented)
-Message: Only contains messages without fails or successes.
-Exception: The error was produced by an unhandled exception that broke the 
test.
-TODO: It's like message but there is a TODO word inside the message's text.

Parent nodes should show the pending type:
-No results: The children are all messages or TODOs.

This task includes the creation or search of the icons.
