WOO-790, WOO-791

* Renamed logging methods.
* Considering removal of the "globals".
* Logwriters are now using Ecom2 and the severity enums.
* Renamed canWrite to writeLogEvent.
* Enforcing loggers to enable on a properly configure path (not necessarily in the public writable space).
* When something goes wrong with the filelogger, we will fall back to nonelogger and...
* ... when logger fails to write via ecom2, it will log critical notices via WC_Log and notify users if in admin.
* Critical severity removed due to missing severity in ecom2.
* Moved log_dir from "advanced merchant" to main tab to visually show that the variable is required to enable logging.
* Disabled order_instant_finalization_methods due to issues with loading on adminpage (methods). Since most of the internals is using ecom1.
* Disabled annuity section due to ecom1 problems.
* getAddressField-controller should not be loading in admin (but it is currently residing in globals-script, which may be wrong from an admin point of view).
