from pd-l2ork: 7ad47e188a941508b92e3c96bc9e05432fbb88f7

got a very early working version that does _all_ object text editing (arrow keys, selection, etc.) in the GUI. (However, it still depends on g_rtext.c for doing everything else.)

*added legacy behavior for key* family of objects where autorepeat is observed (just create an object with an optional argument of 1)
*fixed bug where gatom after pressing return should not stay focused
*fixed bug where gatom's number after ctrl+click should not turn selected
*offered ability for image and others to ignore clicks and pass them below (measured by a zero width, only works for single inlet/outlet objects as otherwise their multiple inlets or outlets will be truncated to the same spot)
*reenabled ability for cnv to pass clicks below and reflected this in the official help file (separate previous commit)

*fixed incorrect sizing of an object that used to be valid with a number of connections greater than the new, invalid object name (including empty object) that happens upon retexting the object, as well as during undo and redo.

*fixed positioning of autopatched objects that were placed immediately below typed objects that have not been activated yet.

*TODO: why is alsa's snd_ctl_card_info_free(info) causing double free error (valgrind's "Adress  is is 40 bytes inside a block of size 376 free'd)? No clue. But with that call disabled, everything works as it should and valgrind reports no further errors.

*fixed preset segfault when doing clear on a hubless node
*clean-up

*made startmotion more user-friendly by hiding iemgui's handles after initial creation until motion is complete. LATER get rid of this because it is likely to be seen as an interim hack due to determinacy issues between the gui and core engine.

*more thorough fix for the preset_node's second object getting incorrectly invisibly connected back to the preset_hub

*cleaned nlet highlighting code (removed redundant call)
*updated TODO
*adjusted startmotion offset (may need further tweaking)

*provided preliminary solution for parsing $0 inside messages (first need to check if this will cause regressions)

*fixed consistency check failed: glist_findrtext when enabling gop and dragging its size around with other text objects on the canvas
*refined checking of gop size due to its text not being hidden, including after saving it to file (from Untitled to something longer, for instance)

*improved drawing logic for all text objects so that they draw themselves during vis process as selected (if they are already selected). This should be the logic for other objects as well: draw yourself normal or selected (check at vis time, only if being drawn for the first time, including after vis 0, followed by a vis 1), and then make sure to tag ourselves as "selected" so that if immediately being displaced, everything indeed follows us as it should.
