Florian Müllner 6257e64d03 shell-entry: Add API to support entry context menus
Add addContextMenu() to support context menus on right-click/long-press.
Depending on the parameters passed, the context menu only contains
"Copy"/"Paste" actions or an additional "Show/Hide Text" toggle action
for password entries.
