Search algorithm should favor adjacent characters

[eater]

When I type opera into a freshly installed copy of FAST, it returns two app results: OPEn cameRA and OPERA -- In that order.

That's a somewhat unexpected behavior. It'd be much better if FAST gave favorable weighting to results in which more of the typed characters are adjacent. If they're adjacent to the word beginning, that should be weighted too.

Thanks for the feedback. Sounds reasonable - but not sure when/if I find time to do this. PRs welcome!
