Make translations for text on the error page

There are some translations that need to be checked, at the moment these are translations from Google translate, from English into the specific language. The messages can be found on the error page. There are 2 different types of urls where the changed text can be found. One where an url is given that does not exist, but the word in the url has some search result on the site. An example of this is in the first screenshot, the arrows point to the text that is changed. The other is when nothing is found, for example when some nonsense is in the url like. An example of this is in the second screenshot.

The text that is changed, is under site/src/main/resources/Resource Bundle 'messages'/messages_Language_type.properties. And the messages that are changed are:

• search.errorright.title
• search.results.notfounddescr
• search.results.norelatedpages
• search.results.suggestion
• search.errorright.parentlink (Maybe the English and Dutch versions should be changed as well, the value now is Parent page, which is parhaps not a very nice title for it)

These are for the following languages:

• French
• Spanish
• Russian
• Chinese

• German - no longer needed for 7.7
