Improving/Fixing count-query

I nearly searched my head off why some queries do and some don't work with ajaxtables until I found.

While

works, this

does not! I like to format those queries a bit with newlines, especially if they are a bit longer than the example above.
But in ajaxtable.module line 358 the count is calculated as:
$count_query = preg_replace('/SELECT (.*) FROM/','SELECT COUNT(' . $count_inner . ') FROM',$table['query']);
This does not match the second alternative above and so the "empty"-phrase is shown everytime.

I would suggest to turn the pattern into:
$count_query = preg_replace('/SELECT\s+(.*)\s+FROM/i','SELECT COUNT(' . $count_inner . ') FROM',$table['query']);
which allows "multiple" (at least one) whitespaces AND ignore case.

Best regards and thanks for a wonderful module
