classes/Bowelyzer.sc: Refactoring all GUI functions, formerly using defer to BowelyzerGUI, where they are all deferred to AppClock. classes/BowelyzerGUI.sc: Adding helper functions to properly defer all needed functionality to AppClock. Renaming setChannelName to setChannelText. The function setChannelName now renames the channelView, whereas setChannelText renames the TextField of a channel.
