Running pyicontract-lint without linting errors should notify success
Hi @mristin , it's me again :)
Just an enhancement proposal: when I got the package to run I had no linting errors and therefore the package would not give any output, even in `--verbose` mode. I had to run it with `--verbose json` mode to get the following output:
```bash
> pyicontract-lint --format verbose telereddit  # no output
> pyicontract-lint --format json telereddit
[]
```

It would be great if we could get some sort of feedback on the successful run (at least in `--verbose` mode). I'm thinking of something along the line of:
```bash
> pyicontract-lint --format verbose telereddit
--------------------------------------------------------------------
Checked xx files. OK
```
