bugfix #221 - java constructor is not called in UIApplicationDelegate implementation

History java constructor is not called in UIApplicationDelegate implementation #221
Fix PR #222

UIApplicationDelegate is being created from native side. And it is constructor is not called so all instance members are not initialized. Yep same #894. But why? Two reasons:

• constructor callbacks are generated for classes marked with @CustomClass annotation (there is 0% of UIApplicationDelegate has this in code)
• even if it is annotated there is no @Method annotation at default constructor of NSObject so it will be skipped

Fix does:

• adds @Method annotation to NSObject default constructor. But this will require developers to use @CustomClass which is lame and against today tradition not to.
• adds sugar during at compilation level. Compiler will consider any class that implements UIApplicationDelegate as @CustomClass (user has not to) and generate all required callbacks
