Enhance the thread hole feature:
- add Config setting to dimension to the point of the hole by default
- For every thread diameter:
In the Model and in the Model Tree: make it visible whether the hole is a M, UNC, UNF etc thread for instance by using different colors for each type of hole
- Thread length and hole depth values: make them availabe in the top of the dashboard to fill in the values: now you have to switch to 2 windows to fill in both
- In practice: The Bore depth is dependant of the thread length and thread diameter. So for each diameter of the thread: when the lenght of the thread is changed, the bore depth should be adapted by the system. The values shall be custumizable via standard table (in the current thread tables it is not possible to add relations like for example bore_depth=thread_lenght+5). NB it has to be possible for the engineer to overwrite the default values if he/she needs to.
