Sloth-ci

- CLI: trigger: if no params were passed, an error would occur. Fixed.
- Bed: add_sloth: TypeError is now handled, interpeted as config source is not a file path or a valid config string.
- API: create: TypeError is now handled, interpeted as config source is not a file path or a valid config string. Using absolute path is advised.
- CLI: Message on Sloth CI start added.

- The "-d" ("--daemon") CLI flag removed (it was not working anyway).

- First major version. Changelog started.
