Fixed database.mysqli.inc.patch to make it more generic and less prone to hunk failures

Hello,

First, great module! Very useful!

I redid you're patch on database.mysqli.inc so that it: (1) uses less hunks, (2) conforms to the PECL standards for Drupal core patches, and (3) is patching against the current version of Drupal you're module supports (5.1.x) instead of HEAD.

PS: You should watch that you're editor doesn't convert spaces to tabs automatically. This doesn't conform to PECL / Drupal coding standards and also it makes your patches needlessly large. This can also cause hunk failures on some systems.

Thanks,

James.
