suggestions for improvements on docs for watch.*

[insasho]

Regarding https://revel.github.io/manual/appconf.html#watchers:

1. The docs for watch.mode refers to watchers.mode. This is ambiguous. Which one is it?
2. watch.mode and watch.code both have a dedicated paragraph for Default setting, but watch.templates and watch.routes specify the default value in parenthesis.
3. Are the docs correct in stating that watch.templates and watch.routes both default to false? Watch mode w/o watching templates seems a little silly.
4. Watch seems to be implemented with inotify, which is incompatible with VirtualBox shared filesystems (vboxsf) and some other filesystems. Mentioning inotify in this section might save devs some time.

Thanks!

@insasho 👍 for the improvement of docs. As for the 4th point, have you ever visited fsnotify's home page?

https://fsnotify.org/
From the beginning, fsnotify had users, with Rob Figueiredo testing it on OS X and later adopting it for Revel.

I was not aware that Revel was using fsnotify. Thanks for the pointer. I'm glad to see https://github.com/go-fsnotify/fsnotify/issues/9 is a feature request for adding polling to fsnotify. I still think it would be useful to mention that watch won't work on many platforms from within a VM as this is a common case.

Taken care.
