Sei Lisa ec509b3840 Fix parenthesization of unary minus 
The algorithm for adding parentheses around unary operators was not working properly. It converted a * (-b) * c into a * -b * c, which LSL handles as a * -(b * c).

Fix and add test cases for that. One of the test cases shows an example where the difference matters: 0 * (-1e20) * 1e20 should result in 0.0, but if wrongly parenthesized, it gives NaN, because 1e20*1e20 gives infinity due to float overflow, and minus infinity times 0 is indeterminate.

The addition of parentheses has been improved, but it still does not eliminate every redundant parenthesis.

Also fix the horrendous typo of using "operands" where it should be "operators".
