{{Quickfixn}} Code generation for admin messages in FIXT11.xml

[Grant Birchmeier]

I disagree with the word "disappearance", as that implies that these
classes were ever generated for FIX5 in QF, which is not true.  Sorry to
nitpick on that.

The simple answer is: We don't generate these admin message classes
because, per recommended usage of the library, nobody needs them.  We don't
need them for our projects, and we don't often hear from people who need
them, and certainly nobody's ever offered to pay us to put them in.

(QF is open source.  People don't often pay us to improve it, so we don't
spend our free time writing things that we don't need.)

Per recommended QF usage, when admin messages are needed, the engine
automatically creates and sends them.  At no point are users of QF expected
to create Logon or Heartbeat or Reject messages in user code.  Why would
anyone need to do that?  Usually when someone needs that, they're doing
something weird or unorthodox.  We simply don't have the resources to give
no-cost support for weird edge-cases like that.  There are many other items
with higher priority than that.
