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 3bc6fd8480847fa5b7dc1d3487324e37cf9c971c to 578ded8d2ad3c1db2403892469a3e7e8bed223af 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.
