Multiple fixes for Apache module and SQL
- Return strong type from functions did not work. Fixed.
- SQL blocks were broken because the prepare() function only passed it's 'this' nss and other variables were inaccessible. Fixed.
- Performance improvements in output to Apache. Beats JSP 2X and matches PHP in speed.
- Zero out numeric values before written to by MySQL. MySQL sometimes doesn't fill in the whole integers, leaving us with trash data in high bits.
