[XF 2] Dynamic Avatar Styling 1.0.1

[r3st4rt]

This add-on lets you customize how default avatars should look like. By default it only adds a complimentary gradient, which can be changed in Style Properties → Avatars → Dynamic avatar gradient color function.
If you want to further expand on customizations feel free to edit Avatar public template.

This add-on has been tested on Developer Preview 10, but it is not compatible with Beta 1 yet.
