Rewrote quest bitfield char[128] <-> int64_t[16] logic.

* This should fix the problem with some completed missions being
forgotten
* We no longer explicitly shuffle bits around. Instead we just cast
and copy the full buffer
* Character creation initializes the quest blob with 128 zeroes, since
that happens later on anyway, but we're robust against different quest
flag sizes just in case
* I haven't looked at the actual flag-setting logic, so if the bug is in
there, this won't fix that one, but it does fix the one where the least
significant bit of every 64-bit flag doesn't get saved to the blob
* I'm still cautious about storing the various bitfields as signed
values even though the client does it that way, since while shifting
into the sign bit is undefined behaviour in C/C++, it may *not* be in
C#. And of course the client implementation may just be buggy as well.
