This patch adds the boilerplate code, needed to fetch properties from engines.
In the past we only fetched *languages* but some engines need *regions* to
parameterize the engine request.
To fit into our *fetch language* procedures the boilerplate is implemented in
the `searxng_extra/update/update_languages.py` and the *engine_properties* are
stored along in the `searx/data/engines_languages.json`.
This implementation is downward compatible to the `_fetch_fetch_languages()`
infrastructure we have. If there comes the day we have all
`_fetch_fetch_languages()` implementations moved to `_fetch_engine_properties()`
implementations, we can rename the files and scripts.
The new type `EngineProperties` is a dictionary with keys `languages` and
`regions`. The values are dictionaries to map from SearXNG's language & region
to option values the engine does use::
engine_properties = {
'type' : 'engine_properties', # <-- !!!
'regions': {
# 'ca-ES' : <engine's region name>
},
'languages': {
# 'ca' : <engine's language name>
},
}
Similar to the `supported_languages`, in the engine the properties are available
under the name `supported_properties`.
Initial we start with languages & regions, but in a wider sense the type is
named *engine properties*. Engines can store in whatever options they need and
may be in the future there is a need to fetch additional or complete different
properties.

With the POST method, autocomplete.js does not URL encode the values.
For example "1+1" is sent as "1+1" which is read as "1 1" since space are URL encoded with a plus.
There is no clean way to fix the bug since autocomplete.js seems abandoned.
The commit monkey patches the ajax function of autocomplete.js

When a user selects an unknown or invalid locale by using the search syntax:
!qw siemens :de-TW
Before this patch a UnknownLocaleError exception will be rasied:
```
Traceback (most recent call last):
File "SearXNG/searx/search/processors/online.py", line 154, in search
search_results = self._search_basic(query, params)
File "SearXNG/searx/search/processors/online.py", line 128, in _search_basic
self.engine.request(query, params)
File "SearXNG/searx/engines/qwant.py", line 98, in request
q_locale = get_engine_locale(params['language'], supported_languages, default='en_US')
File "SearXNG/searx/locales.py", line 216, in get_engine_locale
locale = babel.Locale.parse(searxng_locale, sep='-')
File "SearXNG/local/py3/lib/python3.8/site-packages/babel/core.py", line 330, in parse
raise UnknownLocaleError(input_id)
```
This patch implements a simple exception handling, since e.g. `de-TW` does not
exists `de` will be used to get engines locale. On invalid terms like `xy-XY`
the default will be returned.
