Wrong rebase? :)

[Deepak, 2015/05/21 14:37:02]

I have done rebase again, and then making the changes in this file asked me to
run 
tools/metrics/actions/extract_actions.py
And after running this the strings that are not added in this file are generated
and getting added.
I checked with "Stars_SignInPromoHeader_Displayed"
This is getting used in EnhancedBookmarkPromoHeader.java file and is not added
in actions.xml
Like this other are getting used and not added in action.xml file.
