add CURRENT_PROJECT_VERSION to Release target to prevent ITMS-90056

[nimajalali]

When importing using Carthage the SDK works fine during development but during distribution the App Store rejects the upload.

App Store Connect Operation Error
	ERROR ITMS-90056: "This bundle Payload/SomeApp.app/Frameworks/Swime.framework is invalid. The Info.plist file is missing the required key: CFBundleVersion."

Since Swime sets the bundle version to $(CURRENT_PROJECT_VERSION) I set the CURRENT_PROJECT_VERSION to be 1 during Release builds.

I've confirmed this resolves the issue but I'm not sure if this is the right approach.

I looked around at some other frameworks and it seems that many just set CURRENT_PROJECT_VERSION to 1 during Release

Sorry for super late reply.
Hmm I'm not sure about this too, I'm merging this since it wouldn't hurt Swime project to have it set to 1
