travis: Add linter to make sure all lines end with a newline character (#68)

Browse Source 
* travis: Add linter to make sure all lines end with a newline character

Ending newlines make line based Unix tools such as `tail`, etc work as expected.

Without ending newline:

```
prompt$ tail -1 ch02.asciidoc
* blockchain to save all transactions vs blockchain as a court system prompt$
```

With ending newline:

```
prompt$ tail -1 ch02.asciidoc
* blockchain to save all transactions vs blockchain as a court system
prompt$
```

Also, makes `git` not complain about "No newline at end of file" in diffs.

* Add newline at end of file

* Remove trailing whitespace
