- changed back to 'return false;' as other methods heavily rely on false instead
of an empty array as pointed out by @heluecht@pirati.ca
- $fetched_contact should be initialized as an empty array, let's not make this
code more crazier than it already is (see APContact::getByURL())
- Move HTTPInputData::process() into App::runFrontend()
- Pass $_REQUEST (including processed Input) to every Module method
- Delete $_POST parameters at Module post() calls because of $_REQUEST
- Add all dependencies, necessary to run the content (baseUrl, Arguments)
- Encapsulate all POST/GET/DELETE/PATCH/PUT methods as protected methods inside the BaseModule
- Return Module content ONLY per `BaseModule::run()` (including the Hook logic there as well)
