consolidate debug functionality

[johanneskonst]

My plan is to keep only the $config['debug'] setting (so remove the $config['httpclientlog'] one),
move all debug output away from the browser's rendering and into the LOG_FILE (error.log),
and maybe log all stuff fetched from remotes into it's own folder (one file per request).
After that I can put some more effort into fixing #144
Would love to hear your opinions @copperhead57 @kec2 (and others who might find this usefull)

I'm thing that consolidating the two settings is fine.
I think that separate log files for SQL, HTTPClient, Frontend and Application.
I would change the setting to a Log level, in stead of On/Off and I would introduce a logging-framework.
One file per request is better then one file i total because of file size if you want to log Header + Data.
That's my thoughts.

Thanks, good points, I'll have a go on this...
Logging framework might be nice in some big future release, but an off/on/verbose setting could be usefull indeed...
http bit is basically two parts: remarks from the executing code and the stuff that's fetched from somewhere, the former would be right at home in an error.log but the latter should indeed be separate files, I have a POC somewhere i can use for that...

FYI only
while testing my move to php7.4, with debug on.
when in imdb online and requesting a series episode list (eg - https://www.imdb.com/title/tt0898266/episodes/?ref_=tt_ov_epl ) the links are not rendered correctly.
have trace this to sending the $note field back into the html from function _replace_enclosed_tag_traced.
