[PD] more hole fixes

- there is the ISO 273 describing clearance holes, so we need to take these values. Only if we have a size not defined in the norm, we calculate
- add the coarse (wide) type for clearance holes from ISO 273
- add all screw thread sizes defined in DIN 13/ISO 261
- rearrange thread dialog to make it more compact
- change name "fit" to "clearance" as discussed
- add tooltips to the dialog
- fix issue with TaperedAngle dialog field
- change a size name because the norms define "M1" not "M1.0"
