Ideas for new icons

• https://fontawesome.com/icons/caret-left?f=classic&s=solid we have caret-right, caret-up and caret-down already, but could be useful for some closed dropdowns
• https://fontawesome.com/icons/arrows-up-down-left-right?f=classic&s=solid and https://fontawesome.com/icons/arrows-left-right?f=classic&s=solid Useful for drag and drop alternative buttons
• Bells for https://design.xwiki.org/xwiki/bin/view/Proposal/Notificationwatchbuttons#HUsingbells
• Square minus and square plus for an alternative for dropdowns. It could be useful for the object and class editors which ATM use silk icons https://fontawesome.com/icons/square-minus?f=classic&s=solid
