Eric Cornelissen 93425f8aa0 No longer require no final newline in SVGs (#1682)
* Introduce newline into a SVG

for testing purposes

* Remove potential newlines from SVGs when building the package

* Don't lint SVG files

... so it is neither required to have, or not have, a final newline

* Remove both Windows and Unix style newlines in build script

* Rever 3372ca3
