redis.Redis.from_url(url) doesn't check if the url is valid
Before this commit: actual error are detected later when the client is actually used.
With this commit, client() makes sure to return a valid Redis client or None.
Also, the code makes sure not to log the password of the Redis URL
settings.yml:
* The default URL was unix:///usr/local/searxng-redis/run/redis.sock?db=0
* The default URL is now "false"
The default URL makes the log difficult to deal with:
if the admin didn't install a Redis instance, the logs record a false error.
It worked before because SearXNG initialized the Redis connection when the limiter started.
In this commit, SearXNG initializes Redis in searx/webapp.py
so various components can use Redis without taking care of the initialization step.
Currentty, when oa_doi_rewrite find a DOI in the result URL, it replace the URL.
In this commit, the plugin adds the key "doi" to the result,
so the paper.html can show it.
* Move the datetime to str code from searx.webapp.search to searx.webutils.searxng_format_date
* When the month, day, hour, day and second are zero, the function returns only the year.
no_result_for_http_status contains a list of HTTP status.
These HTTP status are seen an empty result list.
In other cases an exception is thrown as usual.
Previously raise_for_httperror were ignoring all HTTP error,
which make defective engines invisible in the stats.
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

Some desktop screens have this resolution,
and tablet layout takes too much space in this configuration
This PR switch to the table layout for screen width strictly below 1280px.
