When selecting two or more applications, the remove menuitem in Application
menu on JNLP Application Viewer does not have any strings in the variable.

- selecting Application, Applet, Library or Installer

  "Remove Application"
  "Remove Applet"
  "Remove Library"
  "Remove Installer"

- selecting two or more items above

  "Remove"

  But it's actually "Remove " because there is a variable and it's an
  empty char "".

The problem is that translator makes out the message "Remove {0}" as
a sentence with the variable, so the translated message should be a
localized sentence and it may not be realized depending on language
without variable as a noun.

Therefore, the menu item for Remove shouldn't have empty string for
variable even if selecting two or more items. It should have "Entries"
like the button label at the bottom of JNLP AppViewer window when
selecting two or more.
