Installation is broken

[sudoaza]

Hi there, latest commit seems to have introduced a bug.

This line in requirements.txt should not have quotes, or even better update it to work with latest versions from cmd2.

cmd2=='1.0.1'

I've went ahead and fixed the conflicts from @eljeffeg PR, I've tried them locally with the basic example and it works fine.
