Materialdesign: Missing Material text_fields icon

[derked27]

I have:

• [X] [Searched all issues](https://github.com/Templarian/MaterialDesign/issues) to make sure there isn't a request for this icon.
• [X] [Searched the current library](https://materialdesignicons.com/) to make sure the icon doesn't exist.
• [x] Only requested a single icon (or a few near-identical ones) in this issue.

Usage

I would like to be able to use the text_fields icon that is part of the material icons.

Examples

We have format-size, which is the same icon horizontally flipped.

Our is credited to Google, so it looks like they updated this. Should we not update ours?

[Templarian]

Yeah, lets just update ours to match and alias font-size.

[goyney]

Updated and aliased.
