When none of the available languages of an object are listed in SiteLanguageList, one language will be chosen arbitrarily. This can lead to strange effects like urls with seemingly random language for each url element.

Debugging:
eZURLAliasML::choosePrioritizedRow() should show a debug warning when none of the available languages of the object are listed in SiteLanguageList (i.e. when the score is zero for all languages).

site.ini:
We should add a statement to this effect: "SiteLanguageList should always contain all languages you intend to use in a site access."

ez.no/doc:

We should add a statement to this effect: "SiteLanguageList should always contain all languages you intend to use in a site access."
