_includes/guide_wallets.md: * Fix formula given for normal child key derivation to state that public keys must also be provided to the HMAC hash function. This required updating both text and images. * Add one-paragraph warning about ancestor key compromise when the ancestor extended public key is compromised along with a descended private key. Update img/dev/en-hd-private-parent-to-private-child.* to help illustrate this warning. en/developer-reference.md: * Remove %include% of previously-removed file which caused new versions of Jekyll to die.
