Explicitly set spaces settings at the project level
Do not use deprecated delegate method
Use only one activity view controller per UIActivity

On iPad under iOS 6, calling `activityDidFinish:` internally calls -[BITFeedbackActivity activityViewController]. We must therefore keep a reference to the previously created activity view controller else the activity view controller can not be dismissed since a new instance is returned for dismissal. Under iOS 7, -[BITFeedbackActivity activityViewController] is not called for dismissal.

On iPhone, the -[BITFeedbackActivity activityViewController] method is not called for dismissal.
Comply to -[UIActivity activityDidFinish:] requirements
Cleanup base64 code

Use -[NSData base64Encoding] which exists since iOS 4.0 (but is only documented since the iOS 7 SDK).

Fix the feedback activity not being dismissed issue
Fix a bug when creating crash report textual representation

It was working always before, but isn't actually correct.
Merge branch 'base64' of github.com:0xced/HockeySDK-iOS into 0xced-base64 with modifications

- Don't use `base64Encoding` if the SDK is build with iOS 7 as based SDK, since that would cause a deprecation warning
Don't use a category in BITCrashReportTextFormatter

This allows the framework to be used inside another framework.
Hide deprecation warning

Even when using iOS 7 only as base SDK calling `base64Encoding` causes a deprecation warning.
