For 0.2

Subtitle control panel is done.

There are three color for select, red, blue, and white, after click the button then click 'play' button, the color of text will be changed
The text box will show what color you have selected
There are 2 bugs for now:
1, the shadow of the text will be stacked if user clicks the play button more than once.
2, color change cannot be activated by click the default play button in player
