Reducing Repeated Code

##Rationale

##Changed Files
**OnceUxUiAutomatorBase.java**
Added class constants *playPauseButton*, *adOverlayTextView*, *currentTimeView*, *totalTimeView*, *rewButton*, *ffwdButton*,

AdOverlayCountdown.java
BasicCompanionAdTest.java
LearnMoreTestCase.java
Replay.java
SeekControlsTestCase.java
TestPlayStartMess.java
* Implemented class constants
Missed one implementation of playPauseButton
Reducing Repeated Code

##Rationale

##Changed Files
**OnceUxUiAutomatorBase.java**
* moved pauseVideo to superclass

BackgroundingTestCase.java
SeekControlsTestCase.java
* implemented pauseVideo
reducing wait time for some tests

##Rationale
Now that fast forwarding functions properly, the *skipAhead* method has been created and implemented as a way to move through content and expedite testing somewhat.

Additionally, everything has been updated with the changes from master.

##Changed Files
**OnceUxUiAutomatorBase.java**
* moved skipAhead method, tweaked it to be based around milliseconds
* introduced class constants from master branch

**BackgroundingTestCase.java**
**LearnMoreTestCase.java**
**TestPlayStartMess.java**
**VideoFrameTestCase.java**
* implemented skipAhead and/or new constants

**Replay.java**
* implemented skipAhead and new constants
* tweaking to testReplay and setUpReplay

**BasicCompanionAdTest.java**
* renamed to **CompanionAdTestCase.java**, and implemented changes from master
* implemented skipAhead in a separate method *skipAheadCompanionCheck*

**SeekControlsTestCase.java**
* implemented new constants and created a new method *navigateToContent* to slightly reduce length of code
