Depend on Parse 1.4.0 pod

[hokster7]

Parse-iOS-SDK pod has been deprecated in favour of Parse. See CocoaPods/Specs#11294.

Please update when convenient!

There is an issue regarding 1.4.0 as somebody noticed. #20

[hokster7]

:/ interesting.

[pronebird]

I would still vote for switching to 1.4.0 because 1.2 is like few years old and it would be easier to fix PFFile once we use newer SDK.

I have addressed this in a pull request. While I don't have unit tests, using the library seems to work just fine after some tweaks presented in the pull request.

Hey @npahucki, I am checking your PR right now.

This podspec depends on Parse-iOS-SDK which is not good I assume. see https://github.com/CocoaPods/Specs/issues/11294
