Problem

Right now for all content protection rules that are

1. active in the general rules tab and
2. have a corresponding input rule for a given source language (input tab)

the protection rule is active and a warning is given to the user that no valid output rule has been defined.

Exception: "Keep as is" rules, for those no warning was given, as no explicit output rule is needed

Solution

Change behaviour for all rules except "keep as is" rules

For rule to be applied in process of Content Protection 3 requirements should be met:

1. Rule is active in Content Recognition Rules tab
2. For this rule and source language exists record in Active Input Rules
3. For Active Input Rules above and target language exists record in Active Output Rules

Exception is Content Recognition Rule with Keep as is flag set to true. This rules do not require Active Output Rule as we not transforming content in any way in this case.
