Summary: Have Flat Pattern extents as parameters to be used in ie. part lists.

Description: - Move flat pattern extents information to part parameter list. (there already is Sheet Metal Properties for title blocks called "FLAT PATTERN EXTENTS LENGTH" and "FLAT PATTERN EXTENTS WIDTH" which hold the right data, but it's badly located for use).
- common parameter table for part and flat pattern mode (all parameters can be used on both modes).
