Factored layer model out into new Inkscape::LayerModel class. This allows

Inkscape::Selection to use a LayerModel that is not associated with a UI.
Changed the interface of verbs (SPAction) to use a new ActionContext
rather than UI::View::View, again so that verbs may be used in a console
mode.
Modified boolean operation verbs to work in console-only mode.
Fixed up DESKTOP_IS_ACTIVE macro to work in the case of no desktops.
Modified main.cpp to process selections and verbs in no-GUI mode.
Other changes are all consequences of the SPDesktop, Selection and
LayerModel interface changes.
