Correct shared library and plugin link logic, as well as informal text.
Update file server URL, update build resource estimations, correct RPATH
logic, allow for qmake(1) static to shared library changes via CONFIG
argument, correct documentation broken title and index links, correct
shared library install path, install only one set of (correct) plugins,
install the designer shared library (as required by QtCreator), announce
features related to shared linking using qmake(1), and correclty
substitute hard coded paths in prl and la library files.
