* Poller perf: add per device
Fix min, avg, and current values
* Fix up previous
* Fix style
* Rename to device average, we don't calculate min and max, but rather the min/max of the average.
* Remove auth use of $_SESSION
Will break plugins that depend on $_SESSION, Weathermap was already fixed.
Port them to use Auth::check()/Auth::user()/Auth:id()
* revert accidental replacement
* Security fix: unauthorized access
Affects nginx users:
Moved php files outside of public html directory (Apache was protected by .htaccess)
Affects all users:
Some files did not check for authentication and could disclose some info.
Better checks before including files from user input
* git mv html/includes/ includes/html
git mv html/pages/ includes/html/
