Adding a CR in  some files and in others not,  is  a good starting point for a
DOS+Unix mess we all have already seen in many projects.

Patch fixes all files matching (even those comming from grunt's build)::

   find ./searx -exec file {} \; | grep CR

BTW: Same with mixing TAB and SPACE indent styles in one and the same file.  So
if sources are tuched here in this patch, its also fixed.
