static include - support setup.t3s and constants.t3s
.ts as extension is by default used for TypeScript which is why it would be nice if .t3s could be used instead for static includes.

The PhpStorm TypoScript plugin from Sgalinski currently uses / supports t3s which is why I proposed that extension.
However, I am sure if another extension is added, they will add support for it too.
I have to admit though that I am not really a fan of file extensions longer than 4 characters because they are rather uncommon (of course, they are possible though).
t3s itself make sense as t3 would be a reference to typo3 but I would be happy with any extension as long as we are not using already used extensions like .ts for TypeScript.
Feel free to create a own patchset too. Personally I think that extension should then also be available for files like ext_typoscript_setup.txt etc. files
