Konversation 1.2.1 released

This second release in the Konversation 1.2.x release series for KDE 4 adds a number of new features to the bookmarks system and support for reacting to changes in network availability as signaled by KDE's Solid, along with a number of fixes for bugs discovered since version 1.2 was released last month.

Changes from 1.2 to 1.2.1:
* Fixed a crash when cancelling the warning dialog that is shown upon receiving two incoming DCC file transfer requests using the same file name.
* Fixed a crash when using the "Clear Completed" action in the DCC Status tab after having previously used the "Clear" action to remove specific transfers from the transfer list.
* Fixed a crash when using the "Clear" or "Clear Completed" action in the DCC Status tab after creating a mixed selection of removable (e.g. completed, or failed) and non-removable (e.g. sending) transfers and the last addition to the selection was a removable transfer.
* Added a "Bookmark Tabs as Folder" feature.
* Added the ability to open the contents of an entire bookmark folder at once (aka "Open Folder in Tabs").
* Made the default generated bookmark titles more verbose: The Format is now "Channel (Network-or-Server)".
* Added support for reacting to changes in network availability as reported by KDE's Solid subsystem. If the network goes down, Konversation will now no longer make futile attempts to reconnect the affected connections. Instead, it will reconnect once the network comes back up.
* Variable expansion (%B, %C, %I, etc.) is no longer done in text segments recognized as URLs to avoid clashes with percent-encoded characters in URLs copied from web browsers, such as German umlauts.
* Made tooltips for truncated labels in the listview version of the tab bar work again with newer versions of Qt.
* Fixed a bug that caused the Watched Nicknames Online list to show the wrong or no tooltip when hovering a list item with the mouse pointer.
* The default destination folder for incoming DCC file transfers is now the "Downloads paths" configured in System Settings or the equivalent in other desktop environments (under the hood, this is a shared XDG setting).
* Making and then comitting unrelated changes in the Channel Settings dialog could cause unintentionally setting the channel's topic to an older version if someone else had changed the topic since the first time the dialog was opened or while the dialog was open, due to a bug in the code that avoids such external topic changes interfering with concurrent local editing of the topic. This has been fixed.
* The contents of the topic edit field in the Channel Settings dialog will now reflect the selected item in the topic history list until the user starts editing.
* Fixed a bug that could cause user mode changes occurring directly after joining a channel not to be reflected by the channel's nickname list.
* Fixed a bug causing the "Open File" context menu action for DCC file transfer items in the transfer list in the DCC Status tab not to work for incoming file transfers.
* Added support for RPL_HOSTHIDDEN.
