Title: Add expand/collapse triangle icons to Find in Files search results headings

Although this is "bonus work," I'm hoping to squeeze it into Sprint 17 to aid discoverability of the existing expand/collapse feature.

This also cleans up how jsTreeSprites.svg is used:
* Use `` to reduce SVG code duplication
* Use clearer named sprite size/offset constants
* Remove unused (& broken) "disclosure-arrow-*" styles
* Move "ins.jstree-icon" style into jsTreeTheme.less.

I've compared screenshots of the project tree to verify that this doesn't affect the appearance of its triangles at all.
