[SCM] Kaboom - Debian KDE 3->4 migration tool branch, master, updated. 87446012f77962a6bf454b39b94362cb64613dcb

[Modestas Vainius]

The following commit has been merged in the master branch:
commit e6330a446171a656b4228e1b9821495d5233b58a
Author: Modestas Vainius <modestas at vainius.eu>
Date:   Sat Feb 28 19:55:55 2009 +0200

    Add kaboomsettings singleton class.
    
    At the moment the class provides a single point to get KDEHOME paths,
    generates "pretty" paths (with $HOME path replaced with ~), adds support
    for --kdehome, --kde4home and --kde3backup command line options.
