fix for more warnings.

- modifier code was using sizeof() without knowing the sizeof the array when clearing the modifier type array.
- use BLI_snprintf rather then sprintf where the size of the string is known.
- particle drawing code kept a reference to stack float values (not a problem at the moment but would crash if accessed later).
