When updating the libtree, we modify the tree multiple times to avoid
crashes on Linux. These generated events that buffered while the widget
was frozen and resulted in redrawing the same footprint 4-10x.
This reduces the buffering by discarding events that are generated
during the freeze and only redrawing when there is a new footprint to
draw
Also don't load the footprints up front. The whole purpose of the
footprint-info stuff is to have enough info about the footprints to
filter them *without* loading. After that just load individual
footprints as we need them.

This ensures the colors used by the status text pane in the preview
widget are the same as the canvas, so there is a seemless transition
between the two.
Additionally, remove the scrollbars from the symbol preview widget
in the place symbol dialog - they are pointless.
Drop all uses of wxRAISED_BORDER and wxSUNKEN_BORDER from dialogs and
panels used in main frame windows.
Drop use of wxSP_3DSASH options on all wxSplitterWindow definitions.
Minor dialog alignment and spacing fixes.
- Pull out compound widget bits into FOOTPRINT_PREVIEW_WIDGET
- Move all pcbnew-specific bits *inside* pcbnew; implementation should
be private for users
- Make a few class members and inner types private
