Title: Add Blueprint.prototype.insertIntoFile.

* Inserts the provided content into a file (always at the end right now).
* Only inserts once unless `force` option is truthy.

Inspired by `Thor#insert_into_file`.

Future additons will include more options:

* `before` - Insert before given string/regex.
* `after` - Insert after a given string/regex.
