WebUI rewritten in a more modern style, bootstrap is dropped in favour of
plain css/grid. Hand-crafted svgs replace utf-8 glyphs for a more uniform
look and smoother animation. webmanifest added for better mobile behaviour.
No doubt minor tweaks will follow...
resolves#57
User may provide a custom index.html template file to be used instead
of the built-in version. Changes to this file are watched by laminard
using inotify in order to load and compress the custom file for gzip
delivery, reusing the existing method for serving static assets.
This feature obviates the custom css feature, so remove references from
the manual and add a deprecation warning if it is used.
Add a section to the UserManual describing how to use this feature and
including a link to an example using Semantic UI.
Fix all hrefs and vue routes to correctly operate against the
<base href> tag. Add a configuration parameter to override the
content of the href attribute, and describe its use.
