Windows/macOS: Added native.setProperty("mouseCursor", cursorName) Api (coronalabs#83)

* WIN: Added native.setProperty("mouseCursor") API

- Windows: Added `native.setProperty("mouseCursor", cursorName) Api. It allows you to change between all of the supported OS cursors on Windows.

* MAC: Added native.setProperty("mouseCursor") API

- MAC: Added `native.setProperty("mouseCursor", cursorName) Api. It allows you to change between all of the supported OS cursors on MacOS.
