Implemented SSH key upload, tests and all :smile:
Rename everything to upload rather than create
Also, make the key string a required value
Update create_ssh_key_spec.rb
Merge branch 'master' into pm_upload_ssh_key
Renamed to add_key
Added options for giving file path
And also suggesting files from .ssh folder (Mac only right now...)
Renamed spec file
Removed puts
Take user home from ENV
Made .ssh folder more platform friendly
Added more path testing for add-keys
Also fixed some issues with duplicated `lets` in rspec environment
Made test for string given generic...
Need to figure out best way to stub
Fixed spec, made test more generic for travis...
Mocked home location, fixed specs
Bit sloppy, but tests now running on Travis
add-key: small refinements:

- modify the language and upper/lowercasing to sound the same as other
commands
- only suggest public key paths if we have any
- modify the specs as necessary for the above
Merge pull request #64 from pearkes/pm_upload_ssh_key

Upload SSH Key command added :smile:
