generated response includes 12k lines of css

[jf---]

I noticed that when hosting a notebook with voila, that in the initial response, 12k lines of bootstrap css is included. While most js code is cached, this initial response is not and takes little under 3.00 seconds to complete. About 95% of the response data is the css code. It seems low hanging fruit to just link the dependency ( as is done for font-awesome ) or is served as a separate file, such that the browser can perform caching.

this applies to the template:

voila/share/jupyter/voila/template/default/nbconvert_templates/voila.tpl

here the css code is inlined in the template

whereas

voila/share/jupyter/voila/template/gridstack/nbconvert_templates/voila.tpl

inlines the bootstrap css

This reduces the response considerable...

I am not sure #78 is the right solution, but I indeed think we should not inline all the css this way, I'll give it some thought.

Agreed, personally I much prefer your #60 approach, closing the PR, leaving the issue open.

Now that we are loading CSS sepatetely (in master), I think that we can close this specific issue.
