How to handle multiple commands.

[frankcarey]

Running multiple bash commands per ahoy command can be implemented easily using the following:

a && b
if a returns zero exit code, then b is executed.

a || b
if a returns non-zero exit code, then b is executed.

a ; b
a is executed and then b is executed.

This works well, so I don't think we need something more fancy. Added docs to https://github.com/devinci-code/ahoy/wiki/Multiple-line-commands
