fixed issue with attrMap. Since one copy of the map was shared by being part of the Donatello prototype, when we modify the mapping, as in the case of line, which maps stroke-width to CSS border-top-width, subsequent shapes use the same mapping, which is now incorrect. To reproduce this, draw a line followed by a circle. the top stroke of the circle is correct but the rest of the edges will be defaulted to black.
