[kde-doc-english] Keypair creation

[Sten Donslund]

I have just created a personal keypair and uploaded the public key to 
the default server usong Kleopatra,
after the creation and before the upload, I was warned to create a 
revocation certificate.
That is the only reference I can find to a revocation certificate, 
anywhere in Kleopatra.
I believe that either should that warning be removed or a guide for 
creating the revocation certificate
should be provided along with an explanation on how to handle and use 
the revocation certificate.
