PJM d1322e7d1d Refactor GetDocumentExtents() 
CHANGED: GetDocumentExtents() in 'eda_draw_frame.h' now has a bool
parameter "aIncludeAllVisible" with a default value "true" which makes
it behave as it did before adding parameter.  If "aIncludeAllVisible"
is false, the returned bbox ignores some items depending on which
program it is running in.

CHANGED: Made "Zoom to Objects" use only PCB edge in Pcbnew.  This
allows text, notes, etc outside the PCB edge to be excluded in the
zoom calculation.

CHANGED: Added "Zoom to Objects" to Pcbnew main menu, and to RMB context
menus for Eeschema and Pcbnew.
