v2.2.1 released

[enzedonline]

Minor bug fix:

• Bug fix: when clicking directly from one video to another, the target became null instead of the new target video. Now correctly loads target video.
• Bug fix: insome cases, proxies became misaligned if ancestor element of quill root (other than the document window) was in a scrolled position. Now correctly tracks target video positions regardless of ancestor scroll positions.
• Enhancement: alt/title modal - Styles & button icons now configurable via options. Replaced button icon unicode glyphs with svg images for more reliable rendering.
