* Rewrite project file to have relative paths and drop SourceProject
* Redo project error types
* Tidy up and document Project type
* Strip out init command
Initialization logic needed for serve, build, and upload is now
much more clear than it was when these functions were written.
This commit refactors all of them to use a new common_setup
module for all of their initialization that's the same.
Starts work on #55.
This is similar to the previous work in #125. It's gated behind a new Cargo
feature, `user-plugins`. This time, the config gate is much smaller. The
`plugins` member of projects is still accessible when plugins aren't enabled,
but is always empty. Additionally, user plugins are only enabled if there's a
Lua state present in the snapshot context when the `SnapshotUserPlugins`
snapshot middleware runs. This not ever the case currently.
This code has very little possibility of rotting while we focus on other work,
since it'll be guaranteed to still compile and can be tested in isolation
without the feature being turned on.
This one took a little bit of tracking down; the VfsWatcher used to spawn a new
thread and then stall/park forever. With one of the recent changes to get rid of
the extra thread, VfsWatcher started getting dropped, which in turn dropped the
watchers created by the notify crate.
Because the threads only tie back to the VfsWatcher was a cloned
Arc<Mutex<VfsSession>>, everything was fine, except that their mpsc::Receiver
objects were no longer receiving events.
This manifested itself as the file watcher magically not watching any files.
Oops.
* Moved commands into their own folder to reduce `bin.rs`'s size
* Moved all of the VFS-related functionality into its own folder
* Documented a lot of functions, including a few very obscure ones
