Add a watch command to gdrbridge

[stetso]

I am trying to work outside if Gideros Studio but currently the flow of working with gdrbridge is a bit cumbersome: reloading is not automatic (at least on MacOS I have to run play <gproj-file> every time there is a change) and I have to manually fetch the logs with getlog regularly.

If it is not too much work to implement, I would propose to add a watch command (or similar) that does reload on change of any file that is part of the project and streams the logs to stdout automatically. Studio seems to have that functionality already but it could also be part of gdrbridge in my opinion.

The studio doesn't do automatically reload files, but it directly receive logs from the player.
I can't think of any way to make this 'watch' command work in a cross platform manner
