Widgetizing Appfinder

[Eduard Roccatello]

Hello Folks!!! ;-)

I'm porting Appfinder to a widget to make it more reusable than in the
past. After this step we should move the widget to libxfce4util to make
it useful for other modules.

Some examples:
- Panel may use appfinder widget to add new launchers
- Menueditor may use appfinder to add launchers to the xfdesktop menu
- Xfrun may use it for application harvesting
- XfDesktop may use it for add launcher to the desktop.
- As the code improves, Xffm could use it as "Open with.." feature

Xfce4-Appfinder would be only a container with added features :o)

What do you think about it?

Ciao ciao,
