Document: Build LXDE-Qt From Source

[PCMan]

Hello,
Recently many things happen to LXDE.
One of the most drastic changes is the migration to Qt.
Due to poor documentation, it's hard to test lxde-qt.
I just wrote a series of wiki pages for this topic.

LXDE-Qt introduction page:
  http://wiki.lxde.org/en/LXDE-Qt

Build LXDE-Qt from Source:
  http://wiki.lxde.org/en/Build_LXDE-Qt_From_Source

GUI toolkit comparison:
  http://wiki.lxde.org/en/GUI_Toolkit_Comparison

A developer guide for migration from gtk+ to Qt.
  http://wiki.lxde.org/en/Migrate_from_GTK%2B_to_Qt

Hope this helps. The wiki pages are rough now.
I'll try to improve them gradually.
Of course, other contributors are welcomed to edit the pages.

Thank you.
