Cleanups to SFD emitter:

 * Don't emit Fore, SplineSet, or EndSplineSet if a glyph has no splines.
 * Emit a blank line between glyphs.
 * Set the "W" flag on all glyphs to indicate that the width is explicitly set.
The last seems to be what's necessary to get Fontforge to believe in my
"space" glyph.
