Add a few more goals
Update php-mode to latest master

Should fix a few of my indentation issues.
Default to Symfony2 coding style in php-mode

Because it's more-or-less PSR-2, which is what we use at work, and what
I'm starting to use in my stuff at home, too.
Do not strip trailing whitespace when saving diffs

Doing so can damage the diff's integrity, especially when working with
crufty codebases.
