* properly escaped "boxtext" output
* output expanded args for canvasinfo "args"

*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.

*added ability to do shift+home and shift+end to select text inside objects
*fixed manual resizing of subpatches which did not work in the current implementation.

*added redrawing of canvases that have gop enabled with scalars so that they automatically conform as the window is resized (as they should)

*further improvements on the garray selection and redraw--fixed garray contents not remaining selected after dialog properties have been applied
*still need to explore problems with multiple arrays in a single GOP

*fixed segfault when resizing array via dialog (regression from May commit). Still need to work on fittograph logic for situations where there are multiple arrays in the same GOP

change type of scalehandle_new and h_master. Document some structs in g_all_guis.h and change some field sizes.

*tried adding scalehandle_free to the canvas_free class but is currently commented out until we figure out why is this causing a segfault...

*cosmetic fixes to g_canvas.c

remove canvas/glist arg in a bunch of recently added iemgui functions, and introduce iemgui_draw_move & iemgui_draw_config

*fixed handle behavior on iemguis (current implementation is not equipped to deal with config kind of actions, and it does not have to)
*streamlined GOP handles since now draw_select deals with explicit delete before redraw

big refactoring #11 : replaced %lxOBJ by x%lx and removed nlet_tag from all iemgui, among other smaller changes
