This is a very simple patch made possible by the recent changes to how
TextClasses are handled. It introduces a layout-reload LFUN that forces
the current layout to be reloaded and re-read from disk. I don't propose
to put this into the GUI. It's something that will be needed only by
people who are modifying layouts, and it probably ought to come with
warnings: If the layout file can't be read (say you make a syntax
error), LyX's behavior is not terribly pretty. (You can't do very much
at all, since all the layouts are now invalid.) But it is still very,
very useful if you are trying to create a new layout file not to have to
restart LyX every time you make a change.
This is often mentioned on the user list.
Comments welcome.
By the way, there's a bug I introduced regarding layout files that can't
be read. I'm working on that.
