Up to know, the initial weather injection was done in the constructor
of ISimulator implementation. This was to early, since in the best case
the injection was not doing anything and in the worst case, crashed
the application because the plugin wasn't ready yet.
This change also replaces ps_reloadSettings with a specific non-slot
version to avoid code duplication.
The following issues were fixed
* Fixed wrong/missing namespaces
* Fixed obvious typos in documentation
* Documentation not in sync with source code

Global variables are always a bad idea since the order of destruction
is unknown and can cause undefined behaviour. In this case the
global shared pointer can be destroyed before CSimulatorFs9Factory which
relies on it.
