Remove duplicated classes ProjectExplorer::FileWatcher
and QmlProjectManager::FileSystemWatcher, create
Utils::FileSystemWatcher from them, merging the functionality.
Also use in HelpManager/Maemo, reducing the number
of QFileSystemWatcher instances (and thus, shutdown time).
Ignore dumper failures if dumper is from 2.1. This is the case e.g.
for the time being with the Qt SDK 1.1. The type info might still
be available if a .qmltypes file is available.

Having a duplicate prototype chain - once in FakeMetaObjects and once
in QmlObjectValues was unnecessary. Now FMOs don't contain references
which may allow other simplifications.
Previously they were leaked when a qmldump or the C++ exported QML
type list updated.
Just deleting the previous FakeMetaObjects is not an option, as they
might still be used in a QmlObjectValue owned by an Engine.

If there's a library.xml file next to the qmldir file, Creator will
read that instead of trying to run qmldump on the library.
