multiline text fields for user settings [FEATURE REQUEST]

[LePenseur13]

Is your feature request related to a problem? Please describe. For some applications I need multiline textfield user settings. Currently this works only with the format fields. But this makes the settings unnecessarily long, especially if multiple are used.

Describe the solution you'd like multiline test user settings

Would be much appreciated. I am guessing it should be fairly quick to do it.
