Fixes in tmcroads

This fix now shows the correct entry and exit content in the tmcroads-table.
In this sample (show url) the first point has only a positive entry and a negative exit role. The inpos, outpos, inneg and putneg values of the point are now integrated in the requirement-analyse for these roles. After this fix, the first point is complete and correct.
