8. Fixes email-freezing issue that occurs when there are more than 100 or so zones per system

1. Updated the user interface (UI) in the following ways:

a. Added icons to the project, system, and zone lists so as to better indicate to the user what list they are viewing.

b. Added more information to be displayed below the project, system, and zone lists, respectively. For example, below the project list, the client name and location is displayed. Below the system name, the system ventilation efficiency and outside air quantity are displayed. Below the zone name, the zone ventilation efficiency and inputted zone airflow are displayed. Also, the "critical" zone name is displayed in maroon.

c. The quantities of systems and zones are displayed on the forms prior to accessing those lists, respectively.

2. Depending upon which zone unit type is selected (ITU, DFDD, TF, and NONE), certain unused inputs will be hidden so as to simplify the zone input process.

3. The app was tested on OS4.

4. The help was updated to explain the above revisions.
