Log Message:
Update Konversation from 1.4 to 1.5

Konversation 1.5 adds numerous major features over the previous stable
release. Of particular note are support for SASL and client
certificate authentication, all-new topic management UI, overhauled
authentication UI in the Identities dialog, per-tab spell-checking
language settings, user-configurable nick context menu entries, mouse
spring-loading on tabs, all-new versions of major bundled scripts and
improved Ignore and Watched Nicknames systems. Many under-the-hood
changes to improve codec support and general performance, along with
the usual slew of bug fixes all over, further sweeten the deal.
