Cleanup: Convert tabs to spaces and remove trailing spaces

[1480c1]

WIll the patches be okay with the conversion of whitespaces? Mainly about the hashes

Also modified STYLE.md's sed to exclude .git, build,Bin, and png and added a command to append newlines to files if it doesn't have it. I checked the encoder guide and the pictures seem to not be corrupt

[1480c1]

The style job now passes for tabs, carriage returns, and spaces and final newlines

Should we enforce that now?

@1480c1 Thank you for taking the effort to fix the coding style. We intentionally postpone coding style clean up to avoid rebasing of #70. Once it is merge, could you perform clean up again? Thanks.

[1480c1]

Sure!

Can this be updated as it is the remaining PR item for the 1.4 release and now is a good time to make these changes? There was another PR for cleanup (226) that is a bit older and can be withdrawn.

I have excluded all of the files in #70

Hi Chris, PR70 will soon be merged hopefully. It is still preferable to include it for style conversion.

[1480c1]

I can open another PR with files specifically from 70 after it's merged, or would it be preferable to just merge style changes in one commit?

[tianjunwork]

Either is fine. Whatever you think can reduce your effort:)

I can wait, main reason why I wish to merge this is so that in the future my pr's don't include so much whitespace changes
