Optimize issue detection in module list

[adriankirchner]

IMHO there are two parts with potential to optimize issue detection:

1. [EDIT by Keywan] moved to do not scan deactivated modules #35
2. Don't check for active settings not defined in metadata.php
   After enabling the ddoewysiwyg module the "Issue found!" flag persists. This is because this module registers two config values (1, 2) in the onActivate event which aren't defined in the metadata.php. Either this is bad practice and ddoewysiwyg should get fixed or the following part should be removed or mitigated to not raise the "Issue found!" flag:
   

   oxid-module-internals/Core/InternalModule.php

   Lines 429 to 431 in 3ef5180

   	if (!isset($aResult[ $sName ])) {
   	$aResult[ $sName ] = -1;
   	$this->stateFine = false;

Hi Adrian, I totally agree with the first point, maybe it can be fixed in they patch release.

About the second point, I am not that sure maybe it can be fixed in the affected module by registering that variables in the metadata. For me it looks like that module does a kind of dirty hack, I would like to investigate a bit depper into that before doing workarounds for that.

fixed, by ignoring additional settings not listed in metadata
