[KDev4] project settings

[dukju ahn]

Currently project-specific settings such as qmakemanager and
makebuilder doesn't work. It shows proper widget via kcmodule
but all the input widgets are disabled.

Does the project setting is disabled now?

Also some additional question. What is the meaning of
ProjectKCModule::setDeveloperTempFile(), setProjectFileUrl(),
and setDeveloperFileUrl()? I guess its for remote project
but what does the namings, especially *develop* suggest?
