Fix some bugs, add two features

[XAVlER-S]

• bugfix:

  • Fix VerticalWheel measure when mode == AT_MOST;
  • Rename setFriction(float);
  • Add integer overflow check for NumericWheelAdapter;
  • Avoid creating canvas each time drawItems();

• features:

  • Add Justify-Fling-optimization;
  • Different styles of items selected and normal in onconfigureTextView;

• refactor to make it easy to use:

  • Upgrade android build tools;
  • Add default active and passive coeff;
  • Differentiate configureTextView and onConfigureTextView in AbstractWheelTextAdapter;
  • Add int->String function support instead of only format ( cuz String.format() is quite an inefficient method);
  • Avoid depulicate findViewById in item by using tag;
  • Max overScroll control;
  • Extract default text style.
