partially revert 5dcbc3e87d for gii/bootstrap/templates/default (fixes #92)

Indentation in the Gii templates broke completely when the coding style was changed to PSR-2 (most likely because the IDE treated some of the code as a string). This is a partial revert of that commit on the template files. 

The controller was manually fixed cosmetically so there may be some deviations from the real PSR-2 style.
