Two new commands, menuitemeditkeyinput and menuitemspectkeyinput, both
work the same as menuitemkeyinput - only for edit and spect binds.
The new edit keys menu should also work fine as edit key help :)
menuitem[|edit|spect]keyinput text bindcmd
Menuitem, that displays "text" and all keys, that bind "bindcmd" - in
game-, edit- or spect mode.
