refs #6089 setting TTL to 150 seconds instead of 10 to not archive on nearly every request. Makes Piwik faster

refs #6065 remove tracker plugins from config and cache them instead in a file. Wondering which test will fail...

Add feature to persist cors hosts in config, edit in general settings tab and append to API headers if any is set.

added development flag which allows us to not cache static cache and to make some more checks when developers develop plugins

Remove isset and == '1'

; Whether Bulk tracking requests will be wrapped within a DB Transaction.
; This greatly increases performance of Log Analytics and in general any Bulk Tracking API requests.
bulk_requests_use_transaction = 1

idSite===false is not valid use case AFAIK so removing code that deals with that.

Refs #5172 Make sure anonymous user cannot edit segments + rename superadmin to superuser for consistency

; The list of periods that are available in the Piwik calendar
; Example use case: custom date range requests are processed in real time,
; so they may take a few minutes on very high traffic website: you may remove "range" below to disable this period
enabled_periods_UI = "day,week,month,year,range"
enabled_periods_API = "day,week,month,year,range"

This will be useful to keep the piwik.org web analytics reports clean of the demo usage stats
