Additionally 2 Arch_Window bugs were fixed:
* If the W1 value was changed the box tracker was not repositioned relative to the cursor.
* The WindowColor was not applied because of a typo in the code. De current default color is quite dark BTW.
Note that all dimensional values that were not really defaults, but just the last entered values, have been removed from preferences-archdefaults.ui. As a result the layout looks a bit strange. That will be improved in a next PR.
This PR introduces a new get_param function. For its default values it checks a dictionary largely filled by reading the preferences UI files. The goal is to have all defaults in one place to avoid inconsistencies. The dictionary is created once and then stored in a global variable.
Once merged this function will be implemented in Draft and Arch. The get_param function in utils.py will become obsolete.
