DiskUsage: added ability to cancel an ongoing scan. fixes #6801.

Also, progress now goes from 0.0 to 1.0 rather than from 0.00 to 100.00
(to avoid a * 100, followed by a / 100)

DiskUsage enhancement (ticket #3520)

* the volume are now displayed in tabs, mounting and unmounting volume adds and remove tabs accordingly
* the infos (file size, etc..) are now displayed below the graph
* node monitoring tells you when your current view is outdated. (the ticket suggested to adjust the view automatically, but I'll wait for comments on this first).
* Drag&Dropping a file on the graph changes the tabview to the tab representing the volume owning that file.

Code style cleanup.

Patch by stpere:
* Make DiskUsage use Tracker's "Get Info" panel instead of it's own (still
falls back to it's own when Tracker isn't running...)
* Fixed some drawing issues.
* Removed the window aspect constraints.

Thanks a lot! Philippe, please have a look how I changed the license, and the
only coding style violation is that you need to watch out for the 80 chars per
line limit. :-) Great work!

Imported the nice disk usage tool "Guido" into the repo as "DiskUsage". Guido
was originally written by Mike Steed. The code was freely available from his
website at one point, which I am no longer able to find. I believe the license
was a kind of public domain, at least compatible with our MIT/X11 license.

The original code was well written with it's own coding style which was not
very far from the Haiku coding style. I have hopefully adopted it completely
to our coding style. While I did this, I came across several places with
comments for a minor bug which I was able to resolve all. I also found ways
to simplify certain places and I elliminated all non-necessary "inter-class
knowledge" which was used to directly access members of other classes which
should have been private.

All in all, this should be a nice little addition, a useful tool which I found
handy a lot of times. If I should not have added this without first consulting
everyone, please voice your disagreement, and it can be removed it again. It
is not part of the image yet.
