Feature: support custom URL icon
The current version of the TOC extension allow to define custom icon through the property
tocIcon based on the UI Fabric / Fluent icons.
The main idea, is to add the capability in addition to the
tocIcon to specify another icon/image based on a custom SharePoint or Internet URL.
Add the property
tocImgUrl to define a custom image as icon, so that overwrite the
tocIcon one once this latter defined.
- Add a string validator to ensure the string is an URL, in other case, the
tocIconwill be displayed
- Update the readme file and add information about the new option
