[L2Ork-dev] soundfiler improvements

[Jonathan Wilkes]

Hi all,

I just merged some soundfiler improvements into master:

* ported the right inlet from Vanilla

* added much better error reporting for the "read" and "write" flags
of soundfiler, plus the "open" message for writesf~. Now you get
actual information about which flag caused the error, and why. There's
also a warning if the filename looks suspiciously like a flag without
the dash, like "skip".

* errors for read/write/open of soundfiler/writesf~ now report the
*actual* message that triggered the error, along with the error
report. This makes it much easier to figure out what went wrong.

* all (or most) errors now properly report the corresponding object
for proper error links so you can track down the problem. Proper class
names and method names are also reported
