fixes RUL2 syntax errors

Some lines have been corrected, others have been commented out.
In particular, I could not locate any suitable replacement for
0x5SB4b6## in Sec7j_FLEXFly.txt; and could not find correct
rotations in Sec7h_FlexHT-OST.txt
removes duplicate definitions from RUL1

Some intersections had been defined twice. Also fixes some RUL1 errors.
In particular, orthogonal OWR ending in diagonal RHW has been corrected.
