Use a consistent style for declaring the names of struct members in their declarations. Note that this convention was already used in many places but not everywhere. Remove spaces around the text (matching commented arguments) with the advantage that the the spell checking utility skips these terms. Making it possible to extract & validate these comments automatically. Also use struct names for `bAnimChannelType` & `bConstraintTypeInfo` which were using brief descriptions.
