Aligned to guideline, path optimized and some fixes to Blogger, Bluetooth, CloudFlare, CodePen, Delicious, Digidentity and Digital Ocean.

All were aligned accordingly and optimized to the following percentages:

Blogger - 23% and corrected color.
Bluetooth - 1% and corrected color.
CloudFlare - 12%
CodePen - 42% and corrected color contrast.
Delicious + 35% because I added a clipping path, for consistency.
Review it.
Digidentity - 0%
Digital Ocean + 20% No idea how to make it the same file size after
following the guideline.

Updated README with the new file sizes.
