Feature request: Zoom horizontally with Ctrl + mouse wheel #4

This would be really nice!

Horizontal zoom (maybe with Alt or Shift, or when the mouse is positioned over the track names) and Ctrl + / Ctrl - keys would be a nice bonus too, but zooming the canvas with Ctrl + wheel is standard in almost every DAW and would save a ton of time navigating around

For reference: MuSE implemented this on January 5, 2013 https://github.com/muse-sequencer/muse/commit/5fb1cdfe5bdd48406e58441b354fc87d3d3c582e#diff-29b5208099494f67b70a815a1c44979f

Feature/fix: Zoom at cursor! Zoom Ctl+PgUp/PgDown (defaults) and Ctl+MouseWheel now zoom about cursor. (Tim) Eliminated redundant call in ScrollScale::setMag(), by blocking signals. Consolidated all HorizontalZoomIn and HorizontalZoomOut functions into a single HorizontalZoom. Added eight more 'quick zoom' levels to class ScrollScale. Modified all HorizontalZoom functions to pass cursor offset, and use it in ScrollScale::setScale().
