Fingering

[Picander]

Often a violin part has fingering opposite to stem, not always on top of staff
Lilypond 2.1.12 doesn't put the fingering up and down by default (i don't know 
if there is some tweak to do this)
If i force a number to go below the staff (with _ ) it often overlaps other 
objects (slurs, notes) or are too near to the notes

example (see 2nd and 3rd bar endings)

\header {
    title = "2."
}

#(set-staff-size 21)
#(set-paper-size "a4")

\paper { %interscorelinefill = 0
        %lastpagefill = 0
        pagenumber = no
        }
\score {
        \context Staff = violino { \modernAccidentals
                \notes  \relative c''' {
                        \key c \major \time 4/4 \clef violin
