New Tool: Toggle Reference Track

v1.39

NOTE: I`ve noticed since using the new scrub slider and even just loading/ unloading long samples in renoise itself; renoise can be prone to crashing (Win 7 64bit here). Would be great if others could help try and nail down the conditions so it can be reported properly as a renoise bug.

Two main additions along with minor stuff:

–added Scrub Slider: available when reference track is selected so you can change its start play position. i.e you are in pattern 1 in renoise and want to hear the chorus at 1.23 in the song then just move the slider along until you hear the right part playing

–Added a Mid: checkbox so that you can choose between having 2 or 3 buttons in the focus section, for more filter options of reference and song. When 2 bands are chosen cutoff is centred at ~ 700Hz

–In situation when reference track has C#4 note but no instrument number (deleted by accident somehow) : Pressing [L] Will first ask user to confirm the renoise instrument that has the reference track sample, via a new popup gui

–new default note is C#4 as the scrub slider uses renoise sample slices to operate
