Attempt to redo Gstreamer stack
Fixed toolbar added settings toolbar drop-down.  We have a nice skeletal layout now.
Implemented WordWrap with `set_wrap_mode` and Gtk.WrapMode.WORD to wrap text in chatbox applied to TextView().

Added Max Message Size /w Constant (size 200 subject to change) using the `set_max_length` method applied to Gtk.Entry().

Fixed Sizing of Chat Expander with method `set_min_content_height` applied to to ScrolledWindow() using constant (also subject to change).

Fixed Chat Entry and Button size by setting set_homogeneous False on the Gtk.Box (chat_entry_box) container.  Then when adding the components set Expand and Fill to True for the Entry() and False to the Gtk.Button().

Confirmed that the error regarding Gtk.AccelGroup is a sugar warning message and is not something we are responsible for fixing (probably an artifact of the Gtk3 conversion).

Changed obscure paired method names in chat system (like send_chat and add_chat_message) to a more sensible match (send_message & receive_message).  So far only ovc.py has been changed to match, and this may have an effect on another part of the system (yet to be tested).

Figured out some degree of CSS Styling for theming, as well as its limits, and a problem with our use of GtkBox which is supposedly being deprecated in the near-future.
Updated OVC to match revised chat code, may still break in networking so be warned to comment out networking if errors occur for testing.
