Let examples show up in Qt Creator again
Fix an issue where the relative paths in the generated examples-manifest.xml did miss the parent directory, effectively blocking the examples from being shown in the Qt Creator Welcome screen. This broke in commit c403e775f60a, where the exampledirs path was changed from "../../../examples" to "../../../examples/multimedia" and "../../../examples/multimediawidgets". This made qdoc miss the "multimedia" and "multimediawidgets" directories in the generated paths. To fix this, the patch * moves all the multimediawidgets examples to multimedia * sets examplesinstallpath to "multimedia" The unification of directories is needed because there can be only one examplesinstallpath per qdoc project.
