[ardour-dev] recent SVN commits

[Paul Davis]

Some of these changes are potentially substantive in their consequences.
Please report any (undesirable) changes in behaviour you notice. The
changes should be all good.

  * notice new locate requests while servicing old ones (makes a
difference on large sessions)
  * write new session file to a different name then rename. this way if
writing the file fails, the old file still exists. backup file still
created.
  * cleanup handling of input changes at startup (a bit faster now)
  * auditioner connects to first two physical outputs, not hard-coded
names
  * stop AudioEngine (JACK client) at shutdown, as first step, not last
  * start engine before loading session, always - all sessions start
"clean" now (i.e. not marked dirty and requiring a save)
  * fix crash caused when loading one session after another
  * truncate plugin and plugin parameter names in track control area
(this used to make all the control areas grow horizontally)
  
  * rev 1214
