Add a convenient way to run examples

Is your feature request related to a problem? Please describe.
There is no easy way to run examples without manually replacing the contents of main.lua and reverting them back when you're done

Describe the solution you'd like
I imagine a simple run-example script in bash or even lua that works something like this:
./run-example.sh chess-set
It can hold the starter repo main.lua contents in memory, and overwrite the file with the example you pass as command, then once Love2D exits, it reverts the contents for you.

Describe alternatives you've considered
A task runner like just would be really nice here, make life a lot simpler. The reason I suggest this is because the repo will soon have a linter, and possibly also tests very soon (which there none). The devex would be very much simplified by having all of these commonly performed tasks accessible through a unified interface

Good point. This can be done with Bash.

Do you have any thoughts on using a task runner, now or in the future? Also I think a lua script would be better since windows doesn't support bash.

Another reason I say this is because I already wrote a bash script for this purpose that supports hot reloading as well by copying your changed file to the root main.lua. The problem is setting up the watcher which for linux I have used inotify-tools but we'd need to also maintain another for macs.

By using a lua script we can use similar logic to what's there in the hotreloading branch. Check if the user changed the example/xyz.lua file, if so we copy it's contents and paste it into the root main.lua file which updates that file's last_modified and hence the hotreload will occur.

I have implemented a script in both languages here. You can test hotreloading as well.
