[Brian Murray]

It's uploaded and awaiting review by an SRU team member.

** Description changed:

- powerline should depend on python3-powerline instead of python-powerline
- by default for 16.04
+ Test Case
+ ---------
+ 1) sudo apt-get install powerline vim-addon-manager
+ 2) vim-addon-manager install powerline
+ 3) run vim
+ 4) observe the following crash:
  
- ProblemType: Bug
- DistroRelease: Ubuntu 16.04
+ Traceback (most recent call last):
+   File "<string>", line 4, in <module>
+ ImportError: No module named 'powerline'
+ During handling of the above exception, another exception occurred:
+ Traceback (most recent call last):
+   File "<string>", line 9, in <module>
+ ImportError: No module named 'powerline'
+ An error occurred while importing powerline module.
+ This could be caused by invalid sys.path setting,
+ or by an incompatible Python version (powerline requires
+ Python 2.6, 2.7 or 3.2 and later to work). Please consult
+ the troubleshooting section in the documentation for
+ possible solutions.
+ Unable to import powerline, is it installed?
+ Press ENTER or type command to continue
+ 
+ With the version of the package from -proposed there will be no
+ Traceback.
+ 
+ Regression Potential
+ --------------------
+ Little as we are just adding a recommends which has been added the package since zesty.
