Support .cargo/config in project directory

[andybarron]

I have a .cargo/config that enables incremental compilation. AFAICT, this is ignored when building from Sublime.

Quick update: It looks like it actually did work, but since I enabled -Zincremental=.cache and worked on a file in the src/ directory, it created src/.cache rather than .cache in crate root. So maybe cargo is called from the wrong working directory?

@andybarron from what i can see, cargo is called from the file you run build from.
So this should be the same as going to that directory in the command line and running cargo build
@dten ?

[andybarron]

Yes. I think there is additional value to building from the crate root; I would imagine that more complex project configuration options would use paths relative to the root. Such projects would break when building from Sublime!

@andybarron do you have this project on github anywhere so we can try it?
