[FEATURE]: one common endpoint for entire functions + Error handling

[mlipok]

What feature would you like, or what problem are you facing?

I didn't care about it before, but I think now is the right time to sort it out.

A similar principle is already in au3WebDriver project

We also need to:
start using enums like $NETWEBVIEW2_ERR__*, $NETWEBVIEW2_EXT__*
and debug better debug function and debug levels like __WD_Error()

Global Enum _
		$_WD_DEBUG_None = 0, _ ; No logging
		$_WD_DEBUG_Error, _    ; logging in case of Error
		$_WD_DEBUG_Info, _     ; logging with additional information
		$_WD_DEBUG_Full        ; logging with full details for developers

What's your proposed solution?

We should take a look on each function and slowly introduce changes.

Do you want to work on this issue/improvement?

Yes

Any additional context?

We should start to use unified error messages like:

Global Enum _
		$NETWEBVIEW2_ERR__INIT_FAILED, _
		$NETWEBVIEW2_ERR__PROFILE_NOT_READY, _
		$NETWEBVIEW2_ERR___FAKE_COUNTER
