Bug fixed bootstrapping the new OO sequencer and made it play/stop.
Removed bacon for the time being, as unused.
Step buttons flash in time. Also generalised button flash mechanism.
Updated comments. Rearranged code for readability/structure.
Fonts and colours set for the 80s
De-linting
Refactored html/scss such that buttons/led now extend the .flash class, rather than it being declared in the mark-up.
Tapping a pad now causes the stepline to show which steps that pad also appears on.
Shortened .flash timing.
Tapping sequencer buttons now edits the sequence.
Last banged pad now highlighted. 'Selected' state changed from red to green. Red now means 'hit'
Stepline buttons flash when tapped.
Added font-awesome and coloured buttons
Transport controls do what you imagine and they flash when hit. The 'play' button also flashes with the beat.
