bug#1475: Bind a few more common key combinations in mac-key-mode.el

[Brett Hoerner]

In other Mac application it is common to be able to combine Shift with
Command + Direction shortcuts to select text in that direction.

The following is a tiny patch that makes it so you can, for example,
Command+Shift+Left to select to the beginning of the line, or
Common+Shift+Down to select the rest of the buffer.
