[Cin] Re-created and checked in cin.po +

A few hours ago, I created a new cin.po as Andrew had suggested since it was over 1.5 years old and I checked it into GIT. Also, checked in the following small fixes: 1) the warn = 0 instead of 1 in batchrender.C (I missed this and should have found it in yesterday's test) 2) added 1 more tooltip on Dangerous flag setting in appearanceprefs.C and slight re-wording on other one 3) removed the sample/display/interlace printf statements from ffmpeg.C and fileffmpeg.C (I hope that is OK)
