The tag alias #54539 digitalsaviour -> darckhumor has been approved.

Reason: DigitalSaviour is his FA name but DarckHumor is his twitter name as well as his most used name.
Even though digitalSaviour isn't used, I figured this may be required in the future should anyone tag his art incorrectly.

EDIT: The tag alias digitalsaviour -> darckhumor (forum #317732) has been approved by @Rainbow_Dash.
