bogus -I0/include CFLAG

When a minimum number of parameters is specified in the method spec, this
shouldn't be required, but overkill is better than underkill.

This makes JS_IS_NUM() the same as JS_IS_NUMBER().

fixed center(). fixed putmsg() to properly handle CRLF. move(), moveTo(), refresh(), top(), bottom() now apply to child frames. (e.g. parent "car" moves, child "passenger" moves with it)

NOTE: argv[argc] != JSVAL_VOID anymore.
