This PR is the first in a series of probably 3 PRs to fix known hole dialog bugs.
This one fixes:
- the .ui file issues
- readonly status issues of some widgets/properties (e.g. when the hole is through all, disable drill point settings)
- the bug that updateHoleCutParams() overwrote the previously correctly determined hole diameter
- just a trifle: change a function name to fit into the naming scheme
