Custom file type support?

[Michael Ducharme]

Hi,

MikroTik has just added support to change the factory config on their 
routers via TR-069 after deployment. They did this with a new custom 
vendor-specific file type:

How can I add this vendor specific file type as an option in "Files" in 
GenieACS? I believe it has to be in the list along with 1 Vendor 
Configuration File, 2 Vendor Log File, etc.
