include refresh
Update the includes to match the bookmaker docs. All edits are generated; if something looks amiss, I probably introduced a bug in the generator. Please let me know. I was careful to pick up all direct edits to the includes and add them to their bookmaker counterpart. Please take a look to see if your favorites are there. Note that enum and struct members have been shortened to fit on one line. The intent is to provide more verbose documentation online. Let me know if this is too terse.
