Selectable: Meta AND Shift key should allow multiple non-adjacent selections

[Alfgar]

To follow more standard Apple Finder & Windows Explorer behavior.

Code change is trivial:

In .selectable's definition, replace:

event.metaKey

and (for minified version)

c.metaKey

by:

(event.metaKey || event.shiftKey)

and

(c.metaKey [||] c.shiftKey)

, respectively, with parenthesis for proper boolean logic.

This follows Apple Finder behavior (do non-adjacent selection whether Meta or Shift) but it doesn't follow Windows Explorer behavior (do non-adjacent selections with Meta, do range selection with Shift). We'll be implementing the latter as it's much more powerful to do two things with two keys instead of one thing with two keys.

It's all spec'd out here: ​http://wiki.jqueryui.com/Selectable
