cmake-gui: add completion for the names when adding cache entries

Up to 100 completion strings for the names of added variables
are saved in the settings, so it will remember the variables
you are usually adding.
It also ensures that CMAKE_INSTALL_PREFIX is always there, since
this is maybe the one which is set most often.
