[Ovmsdev] Car firmware v1.2.7

I notice that the build in vehicle/OVMS.X/dist/TR_Experimental/ got updated
for 1.2.7, but the build in vehicle/OVMS.X/dist/TR_Production/ did not.

I want to update my firmware update page to include 1.2.7. Should I use the
build from the TR_Experimental directory, do a TR_Production build myself,
or wait for an official TR_Production build?
