Fixed minimum array gop size on the parent window due to the garray text size which was before spilling over the minimum box size and not maintaining proper margins.

* give new cord the same color as selected line (except for vanilla/ext presets)
* make broken object stand out more
* make comment dash sizes match l2ork 1.0
* change xlet hover animation to match new xlet style

fixed segfaults caused by preset_hub_read and preset_hub_readpreset (may want to revisit later to disable the crflag from the binbuf_read_via_canvas and consider implications of potentially running into an A_SEMI which currently does not appear to be likely, or dare I say, possible?)
