Use a separate ES Module based build for the web version of the lib
package. This fixes the rebuild on watched files changing in lib
failing with a TS1479 error.
Remove circular dependency between inventory_sync/message.ts and
inventory_sync/instance.ts by moving the IpcPlayerData type from
message.ts to instance.ts. This solves a problem with the web
build checking types in instance.ts that it dosen't use.
By default webpack-dev-middleware will refuse to delete files outside of
its working directory. This becomes dist/web in the configuration
currently set up, which means that a rebuild triggered on the watched
files will fail when declaration files are output to to dist/web_build.
Fix by moving dist/web_build to dist/web/build.
Clean up the configuration for compiling TypeScript for the Web
interface to us its own tsconfig.web.json config files and reference the
TypeScript source files directly in the configuration and imports
instead of files compiled to dist.
To properly support recompliation with TypeScript's projects feature
each package's tsconfig.web.json file is set to output the build to
dist/web_build which is then ignored in .npmignore. Webpack is still
used to create the proper build in dist/web, so this is mainly to make
TypeScipt's compiler happy but it also allows the root tsconfig.json
file to include the web interface code, meaning running the build script
now also checks the typing of the web interface.
Final part of #491.
