Fix GrampsWeb subpath: patch CSS font paths from ../fonts/ to fonts/ (STI-90)

CSS url() resolves relative to the stylesheet, not <base href>. With
the stylesheet at /ahnenforschung/style.css, url('../fonts/...') resolves
to /fonts/ (root) instead of /ahnenforschung/fonts/. Changed to relative
url('fonts/...') which correctly resolves under the subpath.

Also fixes Material Icons font not loading (menu icons broken).
