Enhancement: Add IsEnabled to Link and LinkGroup

[DaleyKD]

I absolutely love the ModernMenu, but there are times I want to show the steps, but not let the user click it unless all the validation has occurred in a previous step.

For the time being, I've copied all the classes involved with a ModernMenu and added my own property, but this was a lot of work.

#69 If you made this working, why not creating a PR?

[DaleyKD]

What's a PR and how? I've never done anything with Git. I'm purely TFS at work.

A PR is a Pull Request. It is basically where you ask the original author to pull the changes you made in your fork into it's main repository. See the article here for how to create one. You must have committed and pushed some changes to a fork (a copy of the main repo) before.

Did someone implement the IsEnabled property in the LinkGroup class?
