This changes the styling of the user profile popup to be responsive
to mobile devices. In this case it is converted to a modal form using
flex to center it on devices with screen sizes under 768px in width.
Fixes#4669.
In this commit we just adjust the position of user profile popover
opened when we click upon buddy from buddy list to view user profile.
The new position ensures that the little blue border visible from back
due to pointed to message is completely hidden by the popover.
In this commit we remove the extra padding appearing around the
user profile images. This can be only reproduced when opening
user profile from buddy list.
