add missing lib dependency to pd release structure for windows
minor cleanups
added default-flags and centralized flag-dependencies

added flags to undo previous flags (e.g. specifying "-nostderr" will disable any previous "-stderr" flag)

also if one flag mandates others (e.g. "-nogui" needs "-stderr"), this is now done after parsing the args, so:
- "-nogui" will have "-stderr" enabled automatically
BUT
- "-nogui -gui" will leave the "-(no)stderr" flag untouched (defaulting to "-nostderr")

ALSO
- added "-norealtime" and "-nort" aliases to "-nrt" (to make it in-sync with the others -no... flags)
fix typo inusage() msg
fixed infinite loop sending 'auto' to text sequence with no buffer
remove debug printout from text sequence object
fixes for text sequence to deal with commas in a more reasonable way
make canvas_properties() a proper t_propertiesfn

- use (t_gobj*) consistently as the first argument.
- add a dummy second argument, so we don't need to typecast
Moved fdpoll init code into it's own function sys_init_fdpoll() that can be called independently of sys_startgui needing to run, such as in the case of libpd.
tweaks to reverberators
Fix MIDI input to look at pd instance so that calls to inmidi_byte() etc
only go to the current pd instance
Ability to dispatch messages from running Pd patches to loaded tcl plugins.
Merge dnd:pd
improved comment in d_osc.c
lower (much better) early reflection times in rev2~
fix for bug 3613962 - bug with special characters
fixed INT_MIN % -1 bug (reported by Claude Heiland)
new help menu option to open "intro" patch
For some reason the wish script failes if HOME isn't defined.  Fixed
s_inter.c to supply one if there's none.  This is a workaround - really
it would be best to figure out where the tcl script is failing.
got rid og tags file
