Bad spacing (gap) when large interval and accidental

[Hudson Lacerda]

Hi. The code below results in a gap between the last notes.
There is enough room below "d" (bottom staff) to draw the sharp of "fis".

P.S.: Concerning to "beams should not collide with accidentals" issue (#76), I 
think the clashes are a awful bug, since a score with collisions is hard to 
read. One takes effort and time to figure out if a black spot is a sharp or a 
natural, if the duration is eight or 16th note, and so on.
