Use dist/browser as the output of the browser oriented TypeScript build
of packages instead of dist/web/build. This distinguishes it better
from the Web UI bundle which is put together with webpack.
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.
The role of the master server as the party controlling every part of the
cluster is not well reflected in its name and has caused confusion among
users on several occasions. Rename master to controller to better
reflects its role.
