UiAutomator test LifeCycle.java finalized

##Rationale
The newest UiAutomator Test checks the Life Cycle of the Basic Once Ux Sample App.

##Changed Files
LifeCycle.java
* introduced playVideo, pauseVideo, lifeCycleInitialCheck, lifeCycleFollowUpCheck, and stringComparison utility methods
* removed seekTo and lifeCycleCheck utility methods
* defined test methods testLifeCycleAdBreakPlaying, testLifeCycleAdBreakPaused, testLifeCycleContentBlockPlaying, and testLifeCycleContentBlockPaused
Merging local branches to get caught up
Making fixes to LifeCycle.java

##Changed Files
LifeCycle.java
* included TimeUnit sleep strategy
* reordering methods to follow the traditional pattern
* omitting test method testLifeCycleBeforeAdDataReady, as the error that was causing the plugin to crash before adDataReady is no longer a problem.
* omitting test method testLifeCycleEndAdBreak, as it was envisioned to be testing an issue that will be tested in SeekTests.java
* added tags for each test method identifying when they begin and end.
* tweaked playVideo wait time
* added try-catch blocks for the most common UiObjectNotFoundExceptions as they are very easily remedied.
Implementing Universal playVideo utility method in the superclass

##Rationale
With multiple classes defining their own playVideo method making a bit of a mess, I decided to create one that all the classes will be able to call down from the superclass.
##Changed Files
OnceUxUiAutomatorBaseTestCase.java
* New and improved playVideo utility method to be called by most, if not all, test classes. The new playVideo method includes a catch for a UiObjectNotFoundException that will press the screen to reopen the seek controls menu, and then try to press playButton again.
LifeCycle.java
LearnMoreCheck.java
* Removed playVideo utility method definition
* changed playVideo(); calls to suepr.playVideo(); calls.
