[Users] update from slypheed-claws to claws mail

[Lars Uhlmann]

Hi there,

i'm using an very old system with sylpheed-claws 2.5.
But now it's time to upgrade my hardware and also my distribution.
I realized that "Sylpheed-Claws" is now "Claws-Mail". All configuration
files have been renamed to get rid of that "slypheed"-part.

Is there an easy way to import my old settings (plugins, filters etc)
and mailboxes in the current version? Maybe with the intermediate step
of the first Claws-Mail release?

regards
Lars
