Don't update search query unless it has changed meaningfully.

Browse Source 
Changing the search query is quite an expensive operation, so this does some rudimentary
checking to see if the two queries are meaningfully different. At present, it trims the
strings and does a case insensitive comparison.

The query is eventually exploded based on whitespace, so leading and trailing white
space is not important. Also, sqlite `LIKE` clauses are case insensitive, so case
is unimportant. Having said that, I'm not sure how someone will be able to change
the queries case without first deleting and then adding characters (thus inducing
meaningfull changse).
