activity_catch_aphrase.xml:
  - Added a ProgressBar to the top of the screen
    that horizontally fills as seconds elapse
    
CatchAPhrase.java:
  - Added variables used in keeping track of the ProgressBar
  - Created functions:
    -- onPause():
         - Part of the Android lifecycle. Called when the app is 
           partially visible but an indication that the user is
           leaving the activity and it will soon enter the Stopped
           state
         - set gameBegun to false to stop the timer from running while
           the game is stopped
    -- onSaveInstanceState():
         - Part of the Android lifecycle. Called before placing the
           activity in a background state. Allows to save variables
           to recall when the activity is resumed
         - Saved "maxSeconds" and "progressStatus" to properly resume
           the timer
  - onCreate now starts a Thread to handle updating of the ProgressBar
  - Every time the bar is updated, I put the Thread to sleep for a bit
    just to ease up on the processing. This is okay because the Thread
    only needs to do stuff every full second
  - Removed the Timer variable as I assumed this was for the ProgressBar
