Change coding visual style

Change coding style for such as is in other framework files:

http://en.wikipedia.org/wiki/Indent_style#Variant:_1TBS

If you add or change files would have been nice to keep them in one style or adopt a pattern/coding style to make it look good.

And I have such suggestions may helpers divided into those that are important for the system without which it can operate, eg. database.php, url.php, and the rest moved to subfolder in helpers.
Only suggestion.
