changed to using short_name in the ASAR mapper so that sigma0, etc., has polarization as suffix. This is consistent with the radarsat-2 mapper. Also added look direction, and changed the look dir metadata item to SAR_center_look_direction to make it clear that this is only the look direction in the center of the image (for long scenes near the poles the geo-relative look dir can vary significantly).

Merge branch 'tmp' after updating master with changes in subversion (there were
none btw). Explanation as follows: I had done some changes on a file in git and
in subversion, and this caused conflict. Because svn2git works on the master
branch I had to make copy of master in a branch I named tmp. After that 'tmp'
had the latest changes in master. Then I did (in master) 'git revert --hard
<version before I changed the file in git>' and 'svn2git --rebase'. Then I did
(in master) 'git merge tmp', and the svn changes have been added and we are
back to the state of master before updating from svn.
