Bookmark setting to specify delays depending on word length

My small improvement, that help me to read without stumble.

With this I can specify my own delays in bookmark script:
window.sq.wordDelays = [[3, 1], [5, 1.2], [7, 1.4], [9, 1.6], [10, 2], [11, 2.4], [12, 2.8], 3.2]

Explanation: [[max-word-length, delay], ... max-delay]
