Multicolor cell remix remix

remixed from https://www.thingiverse.com/thing:2657524 by https://www.thingiverse.com/Ebola57

increased in size for 0.4 printing:
* Golgi.slt
* Mitochondrion m.stl

Simplified for better slicing and fixed:
* J-Inner-1-fixed

'tail' for the cell to represent the flagellum. poke that beast into one of the spore like holes. or not:
* flag.stl

Also offered are more 'guts' that are unspecified since sometimes a student needs to model additional aspects of a cell - so this grab-bag offers some extended creativity.
