[mod] normalize variable name for the max number of results per request
In the past, we have used different names for the variable that specifies the
maximum number of hits in the outgoing request.
- ``page_size``
- ``number_of_results``
- ``nb_per_page``
Since *page_size* is the most accurate term and is also used in the XPath
engines, all other engines are adjusted accordingly within this
patch .. documentation adjusted accordingly.

Signed-off-by: Markus Heiser <markus.heiser@darmarit.de>
The language_support variable is set to True by default,
and set to False in only 5 engines.
Except the documentation and the /config URL, this variable is not used.
This commit remove the variable definition in the engines, and
set value according to supported_languages length: False when the length is 0,
True otherwise.
