Some bugs involving the Macaulay2-sage interface

1. In a notebook, running sage, the following displays the tex source instead of the formatted tex. 

    m = macaulay2('matrix {{1,2},{3,4}}')

2. interact doesn't work well will Macaulay2, in a terminal window: 

sage: m2 = Macaulay2()
sage: m2.interact()

  --> Switching to Macaulay2 <-- 

macaulay2: R = QQ[x,y]
