Support for the EVE Api

After calling `lillith.initialize`, call:

```python
lillith.Api.initialize('keyID', 'verificationCode')
```
`cacheOnly` was a debugging thingus to allow me to ensure that i never hit the EVE api servers (my edit-run-fix loop was pretty tight and i didn't want to risk EVE giving me a temporary blacklist).  I'll remove this, isn't not useful enough to keep in
