Starts to resolve the chaos of putting version numbers into every
package.json file.
Adds a new keyman-version package which mimics the
version information in build-utils.sh. This will eventually replace
resources/web-environment.
Fixes the build for the lexical model compiler tools to remove refs to
package.json version and use keyman-version instead.
More fixes coming in a follow-up.
This starts the reorg required for splitting the lm worker into its own
module. Tests are still not working. But builds are going.
Some decisions to be made around the final path for wrapping of the
code. I think it may be possible to do something a whole lot more
elegant by moving the wrapping process into the KMW build and leaving
the LM Worker output as a pure tsc output -- given only KMW wants the
wrapped worker anyway (tests aside). The actual wrapping code could
still be in the lm-worker folder.
