Link checker complains about:

• [404] http://everse.software/RSQKit/releasing_code | Network error: Not Found
• [404] http://everse.software/RSQKit/version_control | Network error: Not Found

These have changed at the RSQKit side into respectively https://everse.software/RSQKit/packaging_releasing_software and https://everse.software/RSQKit/using_version_control, so let's change them.
