Set timeout intelligently based on question length

[glutanimate]

Quoting from a review:

I have a sugggestion: It would be absolutely AWESOME to add an option like "add x seconds per word" (add answer time per word on the question card). My deck consists of short words, but also of longer phrases and complete sentences. And I guess since "sentence mining" is a fix term in the language learner community, many other learners also have such a mixed deck. With such an option, many people could use this Anki addon without having to deactivate it each time a longer phrase comes along (and therefore not really being able to use it at all). Anyways, keep uop the good work!
