Allow for multiple FOLLOWING/PRECEDING in a window range

Altered the range specification for window functions to allow
for two of the same PRECEDING or FOLLOWING keywords in a range
by allowing for the left side of the range to be positive
and for the right to be negative, e.g. (1, 3) is
"1 FOLLOWING AND 3 FOLLOWING".
