Rebrand RCE

[ArneBachmannDLR]

Just some food for though...

• The abbreviation RCE is often seen in security advisories for remote code execution, which has a negative connotation
• RCE as a three-letter abbreviation is prone to be used in many other areas and might lead to wrong hits in search engines
• rcenvironment.de as a URL is a bit clearer, but mixes abbreviation for "RC" and a full word "environment", which always seemed odd and distracting to me
• targeting an international audience, I'm not sure if .de is the best suited TLD, but it can be considered trust-worthy and matches DLR's origin, so no complaints here
