Version 1.5.4 - 07.08.2020
- Added the gable wall tool with the ability to draw and edit standard gable walls.

Be advised this is a completely new module with modifications to over 36 files (ruby and html). I have tested most of the features with the gable walls however I am quite positive that further testing will pull out a few bugs or limitations which will need to be rectified.
Please feel free to test out the new gable wall module and report any bugs or other issues that may arise.
The following limitations currently exist and are subject to change in the near future:
- The gable wall cannot be used with the wall "move" tool yet. The results might be unpredictable.
- Gable walls are limited to orthogonal corners (90 degrees).
- Auto-corner configuration is turned off for gable walls, the user can edit the wall once it is created and set the start and end termination conditions.
- I will need to add in additional logic for the case of zero wall height (triangular gable walls).
- Currently there is no method from switch a gable wall to a rectangular wall.
- Termination conditions are: Outside Corner, Inset Outside Corner, End, Terminal, Tee Corner.
