codereview #2: some cleanup, correct use of nothing-events

* return error, don't panic
* skipping status export is an error
* use switch in config.go
* move PromptPassword to input
* move client construction into getIdentityClient
* use non-pointer context throughout client since it is an interface
* remove some TODOs
* don't emit multiple nothing-events, just one per bug only if nothing
  happened.
* rename EditBody to EditCreateComment
* add configuration notes about additional values
* store bug id map in a dictionary in the config
* some fixes from testing
