[POC] Setup Rake task

Because I am tired of doing `bash -l`... for cross repo tests...

Edit:   Well... apparently it is required for anything `nvm` related...
Edit 2: `nvm` seems to install then use, so just makes sense to have
        this as one step.
Edit 3: `nvm` is a function, so have to source it first... ugh
Edit 4: Set PATH for node.  Add spec:cypress:ci exec task (sets path)
Edit 5: Debugging...
Edit 6: Forgot to add `../bin`... derp
