Replace servertree with custom serverview

Would that be possible? If yes, how? :o A similar approach to the tweakUI example?

Btw it seems like there are still some issues with the plugin:

Btw the filetransfer dialog looks good but still needs some work :)

   ``` 5/21/2017 19:20:35 pyTSon.PluginHost.registerCallbackProxy Info Callbackproxy FileTransferModel registered 5/21/2017 19:20:35 Info Error opening file "C:/Users/Timo/Downloads/.flooignore": The system cannot find the path specified. 5/21/2017 19:20:35 pyTSon.PluginHost.unregisterCallbackProxy Info Callbackproxy FileTransferModel unregistered ```

I really like the idea of showing the seconds =)
