One reason for the often seen CAPTCHA of the startpage requests are the
incomplete requests SearXNG sends to startpage.com. To avoid CAPTCHA we need to
send a well formed HTTP POST request with a cookie, we need to form a request
that is identical to the request build by startpage.com itself:
- in the cookie the **region** is selected
- in the POST arguments the **language** is selected
Based on the *engine_properties* boilerplate, SearXNG's startpage engine now
implements a `_fetch_engine_properties()` function to fetch regions & languages
from startpage.com.
This patch is a complete new implementation of the request() function, reversed
engineered from the startpage.com page. The new implementation adds
- time-range support
- save-search support
to the startpage engine which has been missed in the past.
