Improved definition of air duct fittings and inclusion of manufacturer's catalogues

The definition of air duct fittings has been improved. They are now classified as "custom-made" and from "manufacturer's catalogue".

Customised fittings are mainly used to join customised rectangular rigid ducts, although they can also be used for other types of ducts if manufacturer's fittings are not available.

In the manufacturer's catalogue fittings, users can find the fittings, with their references, that each manufacturer has in its catalogue.

With the "Generate fittings" tool found in the "Fittings" menu, the program automatically generates the duct fittings, using the ASHRAE database and choosing the catalogue, the material and the selection of the ducts being connected. If the ducts are custom rectangular rigid ducts, the program generates a custom ASHRAE fitting with the ducts' characteristics. If the ducts are not customised, the program browses the manufacturer's catalogue for the fitting to be used to join those ducts, and, if the corresponding fitting is not found, the program generates an ASHRAE fitting that must be reviewed by the user to indicate the material and selection.
