login command doesn't work on chromebook

[beauraines]

When using the rtm login command, the copy and paste

1. doesn't seem to copy to the clipboard
2. Doesn't accept any input (hit Enter) and just hangs

This is occurring on my Chromebook and should be validated on other machines.

I did note that I had to manually install xclip on the Chromebook to resolve some other errors. Maybe this should be called out in the documentation.
