Adding some Hook

[AdrieanKhisbe]

I'm using global linum mode, so when I open direx, the line number appears. To avoid this I usually use a hook. However after having a quick overview of the source, I didn't found any.
Adding a basic hook to direx woul enable to do this, and any other similar functionnality.
(I would have fork and done it if I knew where best would it be to put it)

There is direx:direx-mode-hook. I guess that can be used.
