Bonnibel used to copy any asset into the root - now a path can be
specified for assets, and debug output goes into .debug so GDB will pick
it up automatically.
Overall, I believe TOML to be a superior configuration format than YAML
in many situations, but it gets ugly quickly when nesting data
structures. The build configs were fine in TOML, but the manifest (and
my future plans for it) got unwieldy. I also did not want different
formats for each kind of configuration on top of also having a custom
DSL for interface definitions, so I've switched all the TOML to YAML.
Also of note is that this change actually adds structure to the manifest
file, which was little more than a CSV previously.
This change moves Bonnibel from a separate project into the jsix tree,
and alters the project configuration to be jsix-specific. (I stopped
using bonnibel for any other projects, so it's far easier to make it a
custom generator for jsix.) The build system now also uses actual python
code in `*.module` files to configure modules instead of TOML files.
Target configs (boot, kernel-mode, user-mode) now moved to separate TOML
files under `configs/` and can inherit from one another.
