- rework the way social links are displayed/editted; we now only allow to
enter a so called "handle" and then substitute that in the final URL
template
- move the "icon" model role to NIM backend
This has several advantages:
- we display only the "handle" and don't have to elide some long URL
- we won't let users enter random URLs into their profile and spoof the
viewing part into clicking it
Additionally, make the social link "button" clickable -> navigate to the
target URL, and make the tooltip behave as "usual" (on mouse hover).
This adds the ProfileDialogView to storybook pages
For now, there's just one control to switch between own profile and
another profile; more to come in later PRs.
The mocked global objects (mainModuleInst and globalUtilsInst) are
injected via QML
