1.5.0: Added IntToLayerMask, marked QuaternionToEuler as obsolete as of 2021 and fixed a couple of bugs

- Drawer: Added IntToLayerMaskAttribute, if a raw int is wanted instead of LayerMask
- Drawer: Added option to either use full or short type name, when using SerializeReferenceTo
- Extension: Fixed issue, where GetValueType and GetValue for SerializedProperty would throw exceptions, if field is private
