Translations:Upgrading from 5.x/23/en

Functionality looking different
In a mixed network you will sometimes see things different on both sides of a link. For example, UnrealIRCd 6 has named extended bans, while they will show up as letter extended bans on the UnrealIRCd 5 side. In the case of such extended bans, UnrealIRCd 6 automatically sends it as letter bans to UnrealIRCd 5 servers, so there won't be any problem. The extbans will work on both U5 and U6.
