in GetMsgPanelInfo() (PPI, scale).
m_image name was confusing: it is not a wxImage, but a BITMAP_BASE item,
and m_image name was already in use in BITMAP_BASE, used inside SCH_IMAGE.
Bitmap properties dialog: show PPI value and add Title to dialog.
Converts dialog_image_editor to panel_image_editor. Embeds this panel in
a new properties dialog for the schematic and PCB editors that allows
editing position, layer, locked status, etc. like other items.
Previous the cross-probing options were mixed between sending and
receiving cross-probe events. This clarifies so that all of the pcbnew
cross-probe options deal with whether the cross-probe is seen in pcbnew
and all of the eeschema options deal with seeing the event in eeschema.
Also updates the wording in the options panels to be the same where
possible and adds tooltips
