First run at adding default image and size to config
Big refactor of how droplets are made
No longer takes defaults from cli, uses ~/.tugboat file.
Fixed authorize spec
Change test environment ~/.tugboat setup
Now adds image, size and region
spec/create: stub requests based on spec defaults
Fix wrong wording for questions for authorize task
Indentation
Config now writes defaults if none given
Now only uses config defaults if none given in cli
Specs now passing, changed to use config defaults
