Robin Dunn 7f60145d85 wxRemotelyScrolledTreeCtrl draws its own lines if wxTR_ROW_LINES flag
is used, but prevents the base class from seeing the flag so they
won't be drawn twice with possibly different colours.

Also changed all tabs to spaces, so the diffs will show a lot of
whitespace-only changes.
