Truncate Text field value in default pretty reporter when needed

[anderseknert]

When violations occur on some very long lines, the pretty reporter prints it in its entirety under the Text attribute. This can cause the terminal output to be wrapped, which makes everything look bad. The following screenshot demonstrates this:

This is the rule that caused this. The wrapping however taints all violations, and not just the one that contained a long line.

We should truncate the output of the Text field to max 120 characters, as that's the default max line length recommendation.
