latest version of mongoose web server library (v6.4) is now implemented in midas. To try it out, edit 
the Makefile, comment-out USE_MONGOOSE4, uncomment USE_MONGOOSE6, make clean, 
make.

After some more testing mongoose v6 will be made the default. (if you see problems, please report 
them here).

Main user-visible change is implementation of pipelined http requests, where the same socket 
connection is reused for many requests (instead of opening a new connection for each request). 
This is supposed to significantly speed up things like ajax requests over https (ssl handshake is 
done only once). (As a buglet, some midas web pages do not generated the "ContentLength" 
header, and force connection reset).

Special features: (implemented in mhttpd.cxx)

- https support (same as mongoose v4)
- https score A- at SSLlabs (if ignore whining about self-signed certificate)
- CORS support (same as v4) (cross-origin AJAX requests - web pages loaded from some other 
web server can make requests into midas)
- password protection (same as v4, uses http digest authentication)
- http-to-https redirect (same as v4)
- setuid-root mode for binding to port 80 (special request from PSI).
