Previously editor would send breakpoints to project whenever
a new breakpoint was deleted or added. Now editor shares a
shared pointer to a breakpoint datastructure. This behavior
is more efficient because it doesn't have to repeatly send
breakpoints everytime one is updated.
Still have to handle cases when a breakpoint is added/removed during
a debugging phase. I also have to figure out how to share the breakpoints
pointer only once per project and editor.
