Reading Mode Improvements

[Rohit Yadav]

Hello guys,

Reading mode has been enabled since a couple of builds now, and it needs more improvements...
First, it needs to have the mode to switch it to Dark mode. 
Second, the Read aloud support needs to there.

Third, support for more font variations, & text colors.

Thank you!

@Rohit YadavAll great recommendations. I would also say that many articles contain embedded Tweets, but in Reading View, the Tweets do not appear, not even the simple text.

@tommyd100 Yea, including the tweet text would make Reading Mode even more better...:grinning_face:

@Rohit Yadav Also, printing from reading mode still isn't working properly (or at least printing to PDF—I haven't tried printing to paper from it yet). It only prints a single 8.5x11 page's worth of the content to the PDF.
