code clean-up and enabling bunch of debugging to hunt down the infinite recursion in the scalar-help.pd (select the left object and observe your own aging process)

*cannot create two structs on the same canvas (otherwise how would you know which one you are talking to)?
*fixed regression where arbitrary font sizes were not honored by the drawsymbols and drawnumbers
*other minor clean-ups
*adjusted help file to reflect the new approach to font sizes

fixed findrtext consistency check error with 2+ level embedded gop scalars (may need further testing for regressions)

first step at cleaning up nested-gop bug (still need to work on scaling the objects to properly fit nested gop xy range)

fixed scrolling algorithm for scalars, improved scrolling logic to avoid unnecessary updates, made scrollbars wider (easier to click) and less transparent

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

added dynamic getscroll call whenever a scalar is altered to ensure proper updating of the srollbars

*fixed segfault (affects all flavors) where creating an expr object with more than MAX_VARS variables (currently set to 9) crashed pd when freeing the object. Example: create [expr 1;2;3;4;5;6;7;8;9;10] as opposed to [expr 1;2;3;4;5;6;7;8;9]. Former crashes when being freed (destroyed), while latter doesn't.

*updated latest additions by Jonathan--still need following fixes:
1) enter-leave demos don't work at all (any demo involving enter-leave)
2) crasher in easing is still valid
3) spin-spin-spin crashes pd-l2ork when trying to close the patch while the image is spinning and being animated
4) curve-bbox is still having accuracy issues (tkpath issue)
5) polar clock still exhibits issues of warping curve (tkpath issue)
6) On the 15.events.pd change call is never issued--is this another side-effect of me not applying everything?
7) Is there a 14. patch for ds-tutorials? I didn't find one.
8) in ds-tutorials is gmon.out necessary or is this a stale file?

additional improvements and fixes for regressions introduced in the last mega-patch by Jonathan Wilkes

fixed segfault regression in 4.datatructures/05.array.pd example where clicking on the scalar array in a subpatch would cause a segfault

*experimental: disabled flow control as per http://article.gmane.org/gmane.comp.multimedia.puredata.general/24447

made mouse click logic ignore comments at runtime to allow clicks to be sent to proper objects that may be under the comments
