Mnemonic for "Open with" clashes with "Open" in File menu.

Use "w" instead of "o" here.

Enable "Edit commands" dialog even if no files are loaded.

Take care not to enable commands, since this would most likely
make no sense.

Remove F8 as default binding for first command.

Remove 'Minimize' from context menu.

Having this option on the context menu is probably superfluous,
as a minimize option is mostly useful as "Oh, look, my boss just
walked in" kind of emergency key.

Set command menu sensitivity in all cases.

Before, they would only be disabled the first time they were
created, not after the editor has been opened again.

Turn cmd manager and editor into module globals.

This allows multiple instances of OpenWithMenu to share
the same objects for synchronized callbacks when the menu
changes.
