Enhancement: md-chips: Using keyboard shortcut "Select All" should select all chips

[cmacdonnacha]

Actual Behavior:

• What is the issue? * Using keyboard shortcut "Select All" (CTRL + A) does not select all chips
• What is the expected behavior? Using keyboard shortcut "Select All" should select all chips. User can then delete all chips at once instead of having to delete each individual chip.

I think this is a great idea.

@topherfangio What do you think?

I would have concerns about what happens if there is text inside the inputbox. It seems like it only makes sense to do this when a chip has focus or when the input field is blank.

if (input.hasFocus || chips.some((chip) => return chip.hasFocus) selectAllChips()

Of course, we don't have support for multiselection for chips, so users aren't able to do ctrl+click, or shift+click, so that would have to be built first.

We're trying to get 1.1.2 ready to push out soon, and this has a lower priority than those issues, so I'm going to bump this to 1.1.3.
