As requested in #277 by Devin. I mark this as a draft because there are small issues that need to be fixed, but 75% is working right now.
- [x] Adding connection works
- [x] Loading existing connection works
- [x] Update existing connections works
- [ ] Show updated list of profiles without restarting the kcm
- [ ] Find a way to use that in initial start (because the whole software is going left-to-right, so pushing an edit page to the right might not be intuitive)
I'm still wondering if using checkboxes for 4G/3G/2G might not be better.
This (partially) reverts commit 127bbdf653.
Only incorrect changes from Kirigami.Units.largeSpacing to
Kirigami.Units.gridUnit are reverted. Only Plasma.Units were buggy.
