Konversation 1.2-alpha3 released

This third alpha fixes a fair amount of annoying bugs encountered in day-to-day usage, as well as a serious bug in handling NAMES messages from IRC servers. We've also made some UI changes that we'd like to get your feedback on: We've changed the default tab completion mode to "Cycle Nicklist", and we've removed the frame around the tab widget when using the listview version of the tab bar.

Changes from 1.2-alpha2 to 1.2-alpha3:
* Worked around a Qt bug that has a text selection in the chat view that includes the last line in the view grow to include the new text when new text is appended to the view.
* Fixed Konversation exposing various signals on D-Bus that it shouldn't have.
* Fixed a regression causing '/names #channel' to end up duplicating the nickname list contents when already attending '#channel'.
* When using Qt 4.5, Konversation no longer paints a frame around the UI elements of a view (e.g. a channel) when using the listview version of the tab bar. Feedback on this change is appreciated!
* Fixed duplicated messages about DCC transfer failures in the chat view.
* When the menu bar is hidden, the top-most item in the chat view context menu is now the option to unhide it again.
* Fixed the OSD disappearing also cancelling the system tray blinking notification.
* Fixed a crash on quit by D-Bus / by KDE session logout.
* Fixed the tab completion nickname list sorting behavior for the "Shell-like" completion modes. The behavior now matches the "Cycle Nicklist" mode and the "Shell-like" modes of previous Konversation 1.x versions again: The last active nick for the given prefix is at the top of the list, with the rest of the list sorted alphabetically.
* The default tab completion mode has been changed to "Cycle Nicklist". Feedback on this change is appreciated!
* Changed the bundled 'bug' script to perform a quick search with the given parameter, rather than try to use it as a bug ID directly. The resulting behavior is unchanged for a numerical parameter, but with a string, much more useful.
* The 'mail' script, which was disabled in the build system up until now, is now getting installed again.
* Fixed a bug causing the "Set Encoding" menu not to work.
* Fixed a bug causing the bundled 'media' script not to work when used to retrieve song information from Amarok 2 for a song which has any of the following meta data fields not set: title, artist or album.
* Fixed the 'Self' field of the DCC transfer details panel not showing the port when available.
* Fixed DCC transfers showing an average speed of 1 TB/s in their first second.
