Pass input data to a CAS program through a file instead of piping it to stdin

Browse Source 
* src/mathed/math_extern.C:
	(captureOutput): redirect stdin from a file.
	(pipeThroughMaxima, pipeThroughOctave, pipeThroughMathematica): use
	"output:" instead of "out:" in the informational messages in order to
	better match the "input:" message from captureOutput.
