// Get Pitch and Bank
// By General Barron (aw_barron@hotmail.com) and vektorboson
// Parameters: object
// Returns: [pitch, bank]
// Returns the pitch and bank of an object, in degrees.
// Yaw can be found using the getdir command.
// Pitch is 0 when the object is level; 90 when pointing straight
// up; and -90 when pointing straight down.
// Bank is 0 when level; 90 when the object is rolled to the right,
// -90 when rolled to the left, and 180 when rolled upside down.
