Binaries that use blindside should not receive a static analysis warning from Apple when uploaded to iTunesConnect

This pull request ensures that blindside will not trigger static analysis warnings during the App Store submission process.

Previously the `perform:` and `propertyName` selectors included in Blindside would trigger warnings from Apple.  Removing these selectors from blindside ensures that blindside will no longer be a source of troublesome warnings when uploading iOS application binaries.
