the function hide was in the header.html file enclosed by script tags. it has
been moved to the theme.js file.
to make it run it was necessary to add a entry point to the WebpackThemeBundle
instance in webpack.py (render the js file) and include the resulting js file
manually in footer.html (to be loaded in the browser).
This commit holds alot of changes in the UI, migration of bootstrap to semantic-ui, override of header.html and setting them for /search & /deposite endpoints. PS. The migration is not finished.
