Suggestion: new extension key

[georgringer]

Hey!

I suggest to use a different extension key "captcha_eu". I registered it in the meantime just so that it is reserved. Reasons:

• shorter
• no need to have the suffix "_typo3" because we are in the TYPO3 universe anyway
• I personally don't like the "captchaeu" with "aeu" ^^
