Add support for .desk file

[ianberinger]

Thanks for sharing your project!
This PR adds support for activating a desk based on the content of a .desk file in the current directory (issue #42).
I updated the documentation accordingly.
Feel free to close if you feel this doesn't fit the spirit of the project :)

Very cool, @ianberinger, and good start. Going to be taking a detailed look at this today or tomorrow.

+1

[mblarsen]

+1 Just what I need

[jamesob]

I'd prefer we go with Deskfile here (resembles Makefile, Dockerfile, etc.).

[jamesob]

Awesome. I'm +1 on this aside from a minor change in naming.

[ianberinger]

Thanks for reviewing. I renamed .desk to DESKFILE and fixed the merge conflict.

[rnewton]

I'm fine with .desk or Deskfile. DESKFILE is really loud.

[ianberinger]

Sorry, my bad. Don't know how I got to the all caps version. Fixed now.

[wricardo]

Really looking forward to this.

[jamesob]

out of date .desk reference

[jamesob]

Feel bad blocking on small comments... I'm ready to merge this thing and iterate, though. I'll hold off on cutting a release after merge because I want to add tests and spruce up the documentation. This is close, folks! Thanks for all the work @ianberinger @rnewton!

Unfortunately this doesn't actually work for me and I've had to revert:

(venv)  [Sat 13 18:41] job/code/desk master* ±
 $ ls Deskfile

Deskfile

(venv)  [Sat 13 18:42] job/code/desk master* ±
 $ desk .

Desk # Description: the desk I use to work on desk :) (# Description: the desk I use to work on desk :).sh) not found in /Users/job/.desk/desks

I'll revisit this feature tomorrow when I have some time to code.

@jamesob, I didn't account for comments in the Deskfile. I fixed that now:

Should I open another PR
