Interactive Schedule formatting and UI improvements

[#1]

To support additional graphical flexibility and visually pleasing outputs with less workarounds to Schedules, architects, designers and engineers managing projects through all design stages, will be able to make additional changes to their interactive schedule formatting.
Here is the list of improvements:

• Hiding/customising Zero values and the hardcoded “---” non-evaluated character
• Further customising the background colours to allow visual grouping of similar fields
• Show/hide units for totals and grand totals, and customize a prefix and suffix for showing a custom unit

This way, users don't need to manually adjust things on the layouts or send their schedules to Excel for further formatting. These improvements will make the workflow easier and meet required formatting based on office standards.
