Remove trailing whitespace, add newlines at end of files

This results in less merge conflicts when using the
Text Editor > Files > Trim Trailing Whitespace editor setting.

.ptex, .mmg and .json files generated weren't modified
as these are saved by Material Maker. These files could be made
to end with a newline automatically on save in a future commit.
