- use KEYMAN_USE_NVM and KEYMAN_USE_EMSDK
- pre-install node (where necessary) to prevent having to do it on each
build
- adjust to current `master`
- fix a few bugs in the Dockerfile
- get required node version from package.json (through
`shellHelperFunctions.sh`)
This change allows to build a docker image that can build Keyman
for Linux with test coverage reports, and installs the necessary
dependencies for running integration tests.
