1.7.5

* Added support for Enums with [Flags] attribute (can set each flag individually)
* Added support for easier bitwise operations on ints (or any primitive assignable to int), and viewing the int as binary. This is intended for things like `Camera.cullingMask`, etc.
* Fixed an issue with Enums that contain duplicate values, for example `CameraClearFlags` (has duplicate values for 2).
