[BioC] problem with ttestFun

I found a small problem with ttestFun in marrayTools which should be addressed.

When all the spots are NA the function returns NA.
But when there is one good spot, the function bombs.

Since you cannot do a t-test with one spot the function should return NA if 
there are fewer than 2 "good" spots.  (Actually, I'd be happier to make 
this 3, but at least you can do the computation with 2.)
