fix(wrapping): Fix fields to wrap instead of truncate at 100 characters

Fields should not be truncated at 100 characters. Instead, they should wrap. The exception is the

first, or summary line of the commit message which is truncated to 100 characters since it is a

summary.

This closes commitizen/cz-cli#4
