Improve code.reactos.org redirection

Issue 1:
https://code.reactos.org/ complains about invalid certificate.
The latter is for [reactos.org] only.

–

Issue 2:
With http or https, [code.reactos.org/] shows [reactos.org/].
But URL remains [code.reactos.org/].
I assume the redirection should be explicit/URL, not implicit/Content.
