Revision 426375

Import some LXQt core components (required by forthcoming update
of x11/qterminal).

LXQt is the Qt port of and the upcoming version of LXDE, the Lightweight
Desktop Environment. It is the product of a merge between the LXDE-Qt and
Razor-qt projects.

This work is based on the LXQt testing repo [1]. Importing is not complete
due to missing pieces in KDE Frameworks (r426118).

I would like to thank contributor and tester, Jesper Schmitz Mouridsen.
