port moonlib/mknob, and fix an iemgui dialog bug with empty strings not getting changed to zeroes for numeric fields

just ship ladspa.h with the external since that header hasn't changed in forever. This makes it easier to build on OSX where we'd have to fetch it with wget/curl anyway

Get rid of some really annoying legacy Tcl commands in the core. As long as we don't have any LED indicators in the console window, show an error for audio dropouts instead. Also get rid of some debugging messages in the pddp.

[r16947] by eighthave: merge in Win32 UTF-8 file/path support
[r16123] by eighthave: pad link fields with -headerpad_max_install_names so the Pd-extended packaging can rewrite the link paths
[r16033] by eighthave: replace verbose() with logpost() since verbose() adds extraneous carraige returns to messages that have been filtered out by the log level
[r15977] by eighthave: bumped to v0.25.2
[r15918] by eighthave: post version message using verbose(0)
[r15472] by eighthave: updated to template/Makefile 1.0.11
[r15186] by eighthave: replace .x%x 32-bit only canvas id with .x%lx canvas id which supports 32-bit and 64-bit

had to revise pdlibbuilder script to get it to build on OSX. Can't really push it upstream as it's just a hack (and upstream has been aware of the problem for some time...)

handle the discrepancy between submodule name "lyonpotpourri" and libdir name "lyon" more gracefully

get rid of erroneous lyon/lyonpotpourri folder so as to start completely over with the lyonpotpourri submodule

shorten lyonpotpourri to lyon in Makefile to match the new submodule name (which itself was changed to match Pd-l2ork)

Add missing dlls to Windows installer, add dynamic lib extensions for Windows and OSX to scripts/load_all_binaries.pd
