Add disabled menu items and make Edit menu context-aware.

- Menu items starting with a tilde ("~") are displayed with COLOR 8 and without hotkeys highlighted. Clicking on them does nothing, but closes the menu.
- Edit menu is now context-aware. Cut, copy and clear are only enabled if there is a selection. Paste is only enabled if _CLIPBOARD$ is not empty.
