This reverts commit bb6e2d93.

The functionality of Master and Slave is now in a single class, which is
currently named Master. NetConfigurables are added and removed in this
class instead of the GUI, so that all applications can now access
NetConfigurables. Due to this change, ConfigProxy has been removed from
reconstruction.

The record button now works as previously. To support this change, a
tagging system based on the one from feature/guienhance has been added.
NetConfigurables are now created as peers connect and removed as they
disconnect, which required changes to ConfigWindow.
