Cleanup: remove spaces from filenames, unix line endings

Also rename "blender export import test suite description.txt" to
"readme.txt" as the filename was including information available
in the leading path.

-Auto Render Regression suite
-==================================
-
-Running
-==================================
-
-./blender -b -P /path/to/tests/auto/render_test_files.py
-
-If desired the blender executable path can be set in test_config.py to
-run the script outside of Blender with:
-
-python render_test_files.py
-
-Results
-==================================
-
-It saves all renders and additional info into tests/auto/test_renders
-The reference renders are in tests/auto/reference_renders
-
-Comparisons
-==================================
-
-Manual comparison is possible, easier is to use automatic comparsion with
-OpenImageIO installed. If it's in PATH then it will be found automatically,
-otherwise the path can be set in test_config.py.
-
-For comparing two Blender versions, you can run the tests with old version,
-copy the .png files from test_renders to reference_renders and then run the
-tests with the newer version.
-
-Notes
-==================================
-
-* test_run.py is executed for each .blend file.
-* The script renders every cycles file twice on the CPU (SVM and OSL).
