Introduce single line / single pattern evaluation for tidal-listener #174
Description
As stated here:
https://club.tidalcycles.org/t/the-atom-plugin-thread/2244/84?u=ndr_brt
No shift-enter, everything is treated as a multi-line pattern so need blank lines between everything. Ok, a good habit to get into anyway
All patterns are sent every time *-enter is pressed, not just the pattern you're editing. No beginning to edit a pattern then make a quick change to another one and go back to the other to finish editing.
