IELTS Only - Version 0.6.3 - Real IELTS Reading Interface Update

- 0.6.0: Build the exact interface of IELTS Reading test

I researched on Google but cannot found any real IETLS Reading interface. Luckily, on YouTube, IDP has posted the instruction for doing Reading in computer-based system which including the real IELTS Reading interface in the video. So I build side-by-side with that.

- 0.6.1: I made the hamburger icon work! Now user can change the theme or text size like official IELTS test.

- 0.6.2: I made a small change in the lower board, user can watch time and adjust the volume that best fit to the user (I know Reading does not contain any sound but anyway in the actual IELTS it also included it)

- 0.6.3: I researched on Google and found that IELTS does not allow to find (Crtl/Command + F) so I make the system listen to that key to prevent it perform find. Copy-paste still works!
