Merge pull request #240 from ksuther/kif-next

Date picker and typing fix for kif-next
Extracted duplicate logic from swipe and scroll gestures and moved it to UIView-KIFAdditions.

Dragging a straight line with a variable number of points is a common
enough use case that it can be broken out of those two tests.
Enabled iPad testing.

There was only one failure on account of action sheets not having
Cancel buttons.  When run on an iPad, the test uses `dismissPopover`
instead.
Moved core functionality from KIFTestCase to SenTestCase (KIFAdditions).
Added details on using KIF-next with other testing frameworks.

Resolves issue #241.
Made SenTestCase (KIFAdditions) loadable.
failWithException should respect stop parameter

It seems as if there was a bug in `KIFTestActor(Delegate) failWithException:stopTest` that caused all exceptions to be hard-coded to stop tests, rather than respecting the passed "should stop test" attribute.

One word fix.

Add note about octest.

By default Xcode5-DP5 set the "Wrapper Extensions" to "xctest", which does not play well together with KIF-next.
