Leaf Tau style change of file type

[etiennelaw]

At the outset: I appreciate the direction Vapor has gone in separating Tau and Leaf. I appreciate that they're seperate projects and I appreciate where they're going are two different places, however:

I believe that there should be a way in Vapor's Leaf to adjust the file type, particularly for XCode development purposes. .leaf files, as we know, do not have the ability to inherit a colour scheme, and, while this is all well and good for experienced devs, sometimes, you can miss things, and I feel that the ability to adjust the file type to be .html would benefit the project.

I don't believe that this is possible with the default implementation of Leaf.
