v1.14.0 - Links to headings, Contents depth, escaped table pipes

Links to headings, a Contents sidebar as deep as you want it, and tables that keep an escaped pipe. Thanks to @rinh (#44) and @SteveHigham (#42, #43)!

New

• Links to headings in the same document ([Install](#install)) scroll to that heading, so a hand-written table of contents works. Headings get the same ids as on GitHub; a link written as the heading text (#Install Guide) or to the file itself (README.md#install) works too. Before, such a link tried to open the document's folder instead. Asked for by @SteveHigham (#43).
• How deep the Contents sidebar goes: All Headings, or up to H2, H3 or H4. Right-click the sidebar, or use Settings > General; both change the same setting. Asked for by @SteveHigham (#42).

Fixed

• Tables: an escaped pipe (\|) no longer splits a cell. It shows as a literal |, inside inline code too, as on GitHub. Contributed by @rinh (#44).
• A closing sequence of # after a heading (## Install ##) is no longer shown as part of the heading.

Install: download QuickMD-v1.14.0.zip below, or brew upgrade --cask b451c/quickmd/quickmd (Homebrew 7 asks for the full name once).
