DataStreamPeer: add missing include <QDataStream>
signalproxy.h: add missing forward declaration of QIODevice
Fix crash with KDE network detection

If the network connection status changed during authentication phase,
Quassel would crash. This is caused by some old bits of code that still
assume that there's always a Peer around, which is no longer the case
after splitting off the AuthHandler.

This commit fixes that issue. Thanks to shadeslayer for the report and
really useful backtrace.

Fix tab completion on exotic platforms

Turns out that using the tab key as an action shortcut in an input widget
does not work reliably on all platforms, at least on OS/2 - sometimes,
the event filter would be called instead of triggering the action.

To make this more robust, we disable the action (just using it as a container
for the custom shortcut) and always catch and handle the key in the event
filter which we need anyway.

Thanks to TeLLie for bisecting this issue and finding the culprit on OS/2.
Fix build on KDE

Oops. This wouldn't have happened with 'auto' :P
Checking for single char line endings

This fixes problems with IRC servers sending only single char line
endings. Before the last char on each line for thos servers would be
chopped, now Quassel checks how the line ends and chops accordingly.

Use correct nick on 001 RPL_WELCOME

Fixes #1020
When the user connects to  a bouncer, the bouncer will send back the
welcome message received when it first connected to the network.
This caused Quassel to display a wrong nick if it had changed
since the first connection.
Adapt CMake logic for finding lconvert in newer Qt5

Seems like Qt 5.3 has added the long-missing lconvert target in its CMake
support scripts, however it didn't also add the Qt5_LCONVERT_EXECUTABLE
variable to go along with that. Adding the target disabled our workaround,
breaking translation support in Quassel.

We now also cover this case (and made things future-proof in case Qt5 ever
adds the variable upstream).
Silence deprecation warning from CMake 3.0+

Setting COMPILE_DEFINITIONS_<Config> has been deprecated since CMake 3.0.
However, the "proper" way of doing things now (generator expressions) have
been support only since CMake 2.8.10, and we require 2.8.9 currently.

Thus, we explicitly enable OLD behavior for CMP0043.
Fix support for CMake < 3

Meh. Apparently I can't just set behavior for future policies, so we
need to ensure that we're actually running CMake 3.
