Add plugin system support, to facilitate the addition of custom features, or create a markdown of tampermonkey plugins list

For some users who use search engine style modification plugins, merging them one by one into the trunk to achieve compatibility can be confusing

With plugin system support, or I also suggest the project create a markdown file of tampermonkey plugins list, we can use tampermonkey to achieve some style compatibility, without merging to the trunk

that's a nice idea
