Doc: Fix various problems in Qt Quick Dialogs documentation

This change fixes the following things in .qdocconf:

    - CamelCase for project name (required for generating valid tags
      in example manifest file).
    - Proper selector for QML Types topic
    - Fix exampledirs to not pull in all the Qt Quick examples
    - Add examplesinstallpath to make Qt Creator see the examples

Also fixes the paths in example docs according to changed exampledirs.
