Move Valid Reads Toggle Into Views Section

[ThatTwat3000]

I think page views and valid reads are more closely related than valid reads and readers gained.

Page views = how many times people have looked at your novel
Valid reads = how many times people have read your novel (based on them sitting on a chapter for at least 30 seconds)

Currently, to find valid reads, you have to go to Statistics > Readers > Valid Reads. It would make more sense to have it as Statistics > Views > Valid Reads.
