Pd Vanilla commit 98b4959f03f0fd9acfd7c117d8061589504c89e6

Bump vanilla compatibility version due to an API change in the loader extension interface (rev. b66acec3 in vanilla).

Add a proper Pd-l2ork version number, which serves to identify official releases and the particular Pd-l2ork flavor (1.x for classic Pd-l2ork and 2.x for the nw.js a.k.a. Purr Data version).

port c87e5b00229eb17bac8dc3047cd9d5f4a42c6711 from Pd-l2ork: hopefully made build process require autoconf 2.5 or newer

add defines for sys_open, sys_close, sys_fopen and sys_fclose as placeholders until the code to handle utf-8 filenames on Windows gets ported

add gui_x for sending hex value inside an array to the gui. Not sure if this is really necessary, but it makes it easy to send a list of open windows for one of the extant interfaces

*patch to add [group] data structure and supporting fixes (work in progress with lingering bug of being unable to display data structure arrays properly, see tiger.pd demo patch in data structures)

- nested plots display properly
- plot is vis'd and unvis'd properly when deleting plot or struct
- commented out ugly plot_displace hack-- multiple plots should work just fine
- separated out garray dependencies into class "old_plot".  This way the changes I made don't affect garrays.  _Very_ ugly hack, but it was pretty simple to implement and will be easy to remove later.
- no crashes when non-existent arrays are entered into a [struct] that has scalars hanging around
- template_cancreate ported from 0.45
- added a function to get the offending struct (to use with "Find last error").  Not using it yet, though.
+ For creating scalars using an object box:
- scalar must have initial "float x float y" fields, in that order.  This means you can't accidentally type the name of the hidden garray structs and create a scalar.  (Nor any other structs that only have a "y" field, etc.)
- broken object box returned if the struct has a bogus array template.  (Although currently I'm just refusing to create such a struct.)

implemented improved version of the g_scalar parsing of owner glist to adopt proper repositioning of scalars.
