Fixed some UI bugs, and redesigned some UI elements.

- Changed class structure (added dialogs, cells folder)
- Changed font to Baloo as it has better font height
- Figured out a way to change the font color of max player slider thumb
- Added cursor effect when mouse hover on any button
- Fixed drop shadow bug for lobby view player cell
- Moved drop shadow effect from player cell controller to css
