Switch Google search code to new code

[mkaply]

So we are going to make a simple switch for the search code. We'd also like to rename the engine to make it clear it's using the new code.

Change will be to add -o to the end of the codes:

firefox-b-1-o | firefox-b-o

There will no longer be a separate code (-ab) for using the address bar.

@mkaply thanks for filing. is there a particular date for this to be changed - or effective immediately?

[mkaply]

As soon as you can (no need for a release just for this).

[keianhzo]

@mkaply @cvan we are using browser-search android component for this now so this will be ready as soon as mozilla-mobile/android-components#1563 lands. We will just need to update the AC version.

[mkaply]

Will we be able to use a different code for Reality?

[keianhzo]

@mkaply Yes, we can override any search plugin assets from AC in FxR to use different codes.
