- Fix indentations of section declarators.
- Replace NULL by nullptr when feasible.
- Sort private section: properties first, then methods.

A "hostId" determines the current host and is appended to
the "workingdir", "pkcs11path" and "mw_geometry" settings
in the database. This allows opening the database
on different hosts without wrong workingdir or not
loadable PKCS#11 libraries
Add settings class to access the settings table in the database
Cache values and improve database writes.
Options dialog simplified
Replace getSetting / storeSetting
Unpack option flags to rows in the settings
