Improve handling of local Weaver-UI-Core repo, adding support for detecting the branch or tag name.

[kaladay]

This adds two configuration variables: 1) CI_WUI_BRANCH 2) CI_WUI_DISABLE_LOCAL_PUBLISH

The CI_WUI_BRANCH should allow for a custom branch to be used in the local Verdaccio NPM hosting. The CI_WUI_DISABLE_LOCAL_PUBLISH should allow for disabling the local Verdaccio NPM hosting.

These should be configurable as per the following documentation:
