Open file(s) in new tab to the left

[cheerfulstoic]

I'm kind of pick about how I like to open files in tabs: I generally want the code to the left of the spec. Sometimes if I have a spec open and I want to open the code I could do <c-t>, but that opens to the right and it backwards to the way I expect. If the spec isn't in the first position I can generally gT and then create the tab, but if it's the only one or if it's in the first position I can't.

It would be nice (and intuitive, I think) if I could do <c-T> (shift-t) to open a new tab to the left instead of the right.

Too spacebar heating? ;)
