Support for Command-Delete standard shortcut in editor on Mac

On OS X, a standard editor shortcut for deleting to the beginning of the line is Command-Delete (which is consistent with Command-Left and Command-Right going to the beginning/end of the line). It works in almost every OS X program.

This is a suggestion to add support for the Command-Delete shortcut in Creator on OS X.

(Option-Delete already works for deleting a single word)
