cmake-gui: Remember variable type in Add Entry

Store variable types together with their names in the variable completion
list so that the type is automatically recovered when you select a variable.

Keep variable names and types in separate lists.  This removes the :TYPE
string from completion list and the Name field and makes variable search
easier.  The variable names and types are now kept in two different
settings - AddVariableNames and AddVariableTypes.  Drop the old
AddVariableCompletionEntries setting.
