Printing first line of task's docsting by --list #105

[hirokiky]

Supported issue #105.

I also added a test but I'm not similar with the testing tool 'spec'.
So that, please teach me about it of fix the code If you don't like the addition.

suggest adding an lstrip() there (e.g. "... + docstring.lstrip().split('\n')[0]") to support docstrings that start on the line after the quotes.

@rread Thanks! I fixed it just now.

When a submodule has a default task, the denotation of that task causes a bug in the formatting of that output.

  aws.elb_status           Check Status of all load balancers.
  deploy.deploy (deploy)            Deploy the branch (default=stable) to staging.
  deploy.jenkins           Establish ssh tunnel to jenkins on port 9000 and open Jenkins.

@jthigpen Thank you. You are completely right. I will fix it as soon as I can!.

It seems this bug caused by a task with some aliases, not only the case of 'default task'.
so that when I fix tests, I will add a task decorated with task(aliases=('',)).
Because It is easier to write and understand that meaning than adding a taks having default task.

This pull-request still can be merged with master safely.
I tried with 0bcf45a.

Thanks a bunch! Very useful change :)

Merged this in, rejiggered a bunch of it (there was existing code to handle this display format so I used that), added changelog, and seems to all work now. Just pushed.
