Project info

Similar to #14, it would be nice to get some basic project info, such as the project Synapse ID, etc. while on the command prompt. For example:

```
>>> kiproject = KiProject("...")
>>> kiproject
Project "__project title__" located at syn:syn123456 tracking x files...
```

Or if not directly the print method, we could add something like `project_info()` that prints this.
