with Jam7 Syntax

- Delete math verbs. The math verb is no longer necessary; arithmatic is automatically recognized.
- Delete extra rounding & truncation operators (% and %t , respectively) operating on integer arithmatic. The rounding and truncation operators still work, but are only necessary where there is a real float that is being rounded/truncated. In Jam5, due to various bugs, integers were often converted to floats, so a truncation statement may appear before every integer assignment or computation.
- Unary + Operators: Remove + signs that appear in if-statements. Previous Jam versions generated errors when comparing nulls to numbers in logical or bit-wise logical expressions. These bugs have been fixed, so these + signs (which used an undocumented syntax to cast the variable as an integer) can be removed.
