Announce ALT and WebUI versions in client

This patch announces WebUI and ALT versions in the top bar of
webui-client page. The ALT version is fetched from the ALIB_VERSION
macro in ALT's version.hpp. WebUI version must be passed manually.
Both are stored in a separate json file.

Also cleanup static files, including algorithms.json. It should always
be built against current ALT backend and not stored in the repository.
