Requirement for "last commit" badge on future listings

[arpadgabor]

I just started looking for some interesting projects that I could take some things from, and looks like there are lots that haven't been active for a while and have broken demo links on them. It could be useful to require adding a badge from now on to projects.

Example:

Vuedo - Description- ![last commit](https://img.shields.io/github/last-commit/Vuedo/vuedo)
