JSON schema refactor (#731)
* Remove JsonSchema.clone * Move createProxy function * Group public properties first * Create private version of getPropertySchema * Mark functions as private * Use non-static getValidValueOrDefault * Mark private * Make public validate function not take an info parameter * Remove JsonSchema * Add isValid function * Use isValid for some tests * Fix incorrect type
