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. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@27357 a95241bf-73f2-0310-859d-f6bbb57e9c96
