Smuxi

Smuxi has to split up messages into many pieces sometimes to properly parse and recognize URLs and other things that need to be transformed. The issue is that this leads to overhead when messages get serialized and then send to the frontends. For this reason Smuxi should compact the messages as much as possible before serializing them. When text attributes of different text elements for example match (fg, bg, bold, italic, underline, is highlight) then it should be glued into a single element.
