Allow to explicitly swap node links by pressing the alt-key while reconnecting node links. This replaces the old auto-swapping based on matching prefixes in socket names. The new behavior works as follows: * By default plugging links into already occupied (single input) sockets will connect the dragged link and remove the existing one. * Pressing the alt-key while dragging an existing node link from one socket to another socket that is already connected will swap the links' destinations. * Pressing the alt-key while dragging a new node link into an already linked socket will try to reconnect the existing links into another socket of the same type and remove the links, if no matching socket is found on the node. This is similar to the old auto-swapping. Swapping links from or to multi input sockets is not supported. This commit also makes the link drag tooltip better visible, when using light themes by using the text theme color.
