Add grunt-lintspaces module to check cr-at-end in js files

We are having problems in some files, that don't have cr at the end
of the file. Some other editors are automatically adding it, so it's
highlighting non-existent differences on gerrit when editing.

Add grunt-lintspaces to ensure that all js files end with newline.
Update all the files to end with a CR to prevent these errors.
