#365 separate fixed width text type on lyric sheets

[Anonymous]

Having the ability to add text that will print in a separately definable fixed width font independent of other comments would allow easier addition of things like guitar tabs so they line up better when printed onto the lyric sheet
(also being able to set text size a bit smaller would also help)
i.e.
;intro
;e-------------------------3
;b-----3---------2---------3
;g-------2----------0------0
;d-0-0---------------------0
;a----------3-3------------2
;E---------------------3-3-3
