Add Build description in Timeline

[Itou Akihiro]

Now, HudsonTrac plugin only shows build number, build status, and build time. I hope to have much more build information such as build description.

I made a patch, which shows build description by using Hudson remote API.

Hudson remote API is very powerfull and I guess HudsonTrac plugin will become much better with it.

Not only this patch, I will make these kind of patches to improve HudsonTrac plugin. I hope to have a write access to repository. What sould I do?

(In [4594]) Added support for displaying build description instead of generic "Build succesfully completed" message. Thanks to akihirox for the original patch. This closes #3377.

Thanks roadrunner, to pick up my patch.

But sorry, the patch has one problem. It requires Hudson 1.230 or later.

In case of Hudson 1.222, for example, you can see the following error message at timeline.

500 Internal Server Error (Hudson Builds event provider
(<tt>HudsonTracPlugin</tt>) failed:<br /><br />NameError: name 
'actions' is not defined<p>You may want to see the other kind of 
events from the <a href="/trac/proj/timeline?milestone=on&
amp;ticket=on&amp;changeset=on">Timeline</a></p>)

I make one patch(HudsonTracPlugin.2.patch) to swich process by Hudson version. Will you please check it.

I wonder whether there are many older hudson users or not. I guess it is better to update Hudson in this case. So I think that it's better to describe this requirement in the project page.
