#272 CIF codegen: add SVG code generation to JavaScript code generator.
- Since we can't merge !716 (closed), this merge request replaces it.
- I put everything into a single commit, so history is lost. But, the history can still be found in !716 (closed). I did attribute @riklubking and @gvlit as co-authors for the single commit.
- The last commit by @riklubking to fix the 'download log' button, is not present here. We can do it in a next merge request.
