Stop filtering Gerrti's static resources with OAuthFilter

When static resources (e.g. `woff2` fonts) are reached out from client
they shouldn't be filtered out with OAuthFilter. Note that existing
extensions were sorted and enriched with additional extensions from
Gerrit's `ResourceServlet.java` (see [1] for details).

Note that `html` files are resource files from Gerrit's perspective
however GitHub plugin's functionality relies on processing and
expanding them hence they are from this perspective not static.
