create a branch so I can implement appendParameter()/appendAttribute()
implement appendAttribute() and appendAttributeByRef() where applicable (Request, User, View, PHPView, SmartyView)
add tests for those new methods, plus implement the "easy" tests for PHPView and User.
Merged bob-append branch changes 2a50930f26dfd39837d23358f3ee179d7778aaae...dc50cee44bb7b95a7e27d8459e5498d1d1e9561f into the trunk.
make ConfigHandler->literalize() return actual booleans for values that call for it ("on" "off" "true" "false" "yes" "no").. there were comments stating that it was intended to work this way, but it was returning strings instead of booleans.
