Reduced code duplication with avatar picture loading, by creating two new functions that handle image choosing and thumbnail creation.
two new functions:
bool misc::getOpenAvatarPicture(QWidget *parent, QByteArray &image_data)
QPixmap misc::getOpenThumbnailedPicture(QWidget *parent, const QString &caption, int width, int height)
getOpenThumbnailedPicture opens a QFileDialog to let the user choose a picture file. This picture is converted to a thumbnail and returned as a QPixmap.
getOpenAvatarPicture calls getOpenThumbnailedPicture and converts the result to a PNG byte array.
All three avatar loading functions now call getOpenAvatarPicture
Furthermore Channel Logo and Channel Msg thumbnail functions now use getOpenThumbnailedPicture
