Make it do a full recompile if needed

[m1ga]

One issue with Liveview is that you can change files like images, i18n files or modules. Reacts "Fast Refresh" will fall back to a full reload if you change files outside the React tree

Finally, if you edit a file that's imported by modules outside of the React tree, Fast Refresh will fall back to doing a full reload

It would be a nice addition to Liveview if it would do a full rebuild when you change files that are handled during compile time. It should show a note at the top like "Please wait. Doing a full rebuild..." during that phase. That way you can have Liveview running even if you add new images and it will be instand refreshes for e.g. JS files and a rebuild for e.g. images.
