http access to git repository redirects to https now

Heya,

I migrated git.srcbox.net (and in general other subdomains) to use the
great SSL certificates available from Let's Encrypt. As part of this
migration, git.srcbox.net is now HTTPS only and the HTTP site redirects
to HTTPS.

In case this causes trouble for anybody fetching the gkrellm git
repository, please tell me (it did work for my git client when trying
manually).

FWIW, gkrellm sources are currently available for fetching via all of
the following URLs:

http://git.srcbox.net/gkrellm
https://git.srcbox.net/gkrellm
git://git.srcbox.net/gkrellm

Regards,
Stefan
