Add PageIndicator interface and custom PageIndicatorLine view.

- The current PageIndicator has been renamed to PageIndicatorDots
  and PageIndicatorMarker has been renamed to PageIndicatorDot.
- PageIndicatorDots and PageIndicatorLine implement PageIndicator.
- PageIndicatorLine uses scroll progress and number of pages to
  draw a line of the correct size and position.
- All of these page indicator files are now in a pageindicators package.
