README: Tweak Git-free install command
bin: Update `subl` symlink to `Sublime Text 3.app`
.osx: Add Spotlight settings

Closes #91 and #174.
.bash_profile: Remove ‘autocomplete Grunt commands’

Closes #224.
.brew: Install PHP 5.5
.gitattributes: Disable normalizing line endings globally

Instead of removing `~/.gitattributes` completely, I decided to just comment out the `* text=auto` line. This makes it easier to temporarily re-enable the setting should I ever want to.

Closes #149.
