Make kiwix::Server a simple wrapper around kiwix::InternalServer.

`kiwix::Server` is now a simple exposition of a public API on top of the
private `InternalServer`.

+Static files compilation
+------------------------
+
+Libkiwix has a few static files 'compiled' within the binary
+code. This is mostly Javascript/HTML/pictures necessary for the HTTP
+daemon.
+
+These static files are available in the `static` directory and are
+compiled by custom Python code available in this repository `scripts`
+directory. This happens automatically at compilation time without any
+additional command to run.
+
+To avoid HTTP caching issues, the URLs (to the static content) are
+appended with a `cacheid` parameter (this is called "cache
+busting"). This `cacheid` value derived from the
+[sha1sum](https://en.wikipedia.org/wiki/Sha1sum) of each targeted
+static file. As a consequence, each time you change a static file, the
+corresponding `cacheid` value will change.
+
+To properly test this feature, this `cacheid` needs to be added
+manually to the automated tests and has to be commited. After
+modifying the needed static file, [run the automated
+tests](#Testing). They will fail, but the inspection of the testing
+log will give you the new `cacheid` value(s). Finally update
+`test/server.cpp` with the appropriate `cacheid` value(s) which have
+changed.
