Removed resize requests from render operations.
Connected resize-check signal listener on GUI to handle automatic resizing on change.
Added modular enable and disable operations for toolbar and chat systems to be called by GSTStreamer and network stack at later times.

Removed mediator methods from ovc.py code to account for a change in communication flow between gui and other components.
Fixed logger to logging import name.
Removed temporary stream constant.
Replaced print with logger and added additional logger output for status and debugging.
Fixed alert system to only work when supplied a message.
Added percent constant for DrawingArea preview during send/receive mode.
Modularized visibility toggles for videos and resize on preview.

Added network stack and gststack methods to GUI to integrate all control logic to gui and abstract network stack and gststack for re-use.
Relocated hacky solution separate from main code at bottom (for easy removal later) and finished visibility toggle logic and changes to code that toggles visibility of video components.

Organized the methods according to purpose with appropriate comment labels.
Cleaned resize processes to eliminate redundant operations.
Fixed preview size percent to be decimal.
Added toggle preview button to toolbar to allow hiding the preview window for better incoming video viewing.

Currently the logic implemented only supports hiding the preview drawing area not turning off the local preview stream itself.
An update in the future could improve this.
Added placeholder event methods for connect and disconnect to network, and connect and disconnect incoming video.
Renamed movie_window for incoming stream to movie_window_incoming for consistency.
Added maximum participants to constant, and removed ip_sent variable used in old network code.
Renamed logger according to file for easier error tracking, and set debug level for development version, allowing output to be silent during normal exection.
Temporarily disabled a method until its necessity can be confirmed.
Added grab_focus to submission of messages so message submission via mouse will return the cursor back to the entry.
Fixed true to True for sensitive setting of chat entry, and renamed send_button to chat_send_button, added to self and implemented sensitivity for this object as well.
