Finished the scrollbars. The only thing remaining is for someone who has a better understanding of the pd_canvas.js and how the events are captured, to refactor my registration of events that ensure scrollbars are clickable and the onresize event. Currently, they are embedded inside the pd_canvas.js under the body tag where you will find both onscroll and onresize events.

Continuing work on the scrollbars. The only known thing now remaining is ensuring that the patch window is properly recorded when saving it (under certain conditions it spits out completely wrong values

Finished second stage of the scrollbar implementation and added scrolling with middle click. All scrollbars are now operational and to the best of my knowledge accurate. The only things remaining are: getscroll needs to be called on deselect to recalculate when the handles are erased on objects that have them (we should get rid of these and focus on bboxes instead), responding to maximizing and restoring, and addressing a weird bug where in 0.46.2 patches are saved with larger window sizes under certain conditions.

First checkpoint in implementing custom scrollbars and improving the scrollbar behavior. This is a WIP that requires nw.js 0.46.2.

* 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?)

This is needed to build when some dependencies are installed into
locations outside of /usr.
