Porting to Forester 6.0 [loc-005S]

This forest has now been ported to Forester 6.0. You may need to clear your cache to get rid of stale stylesheets or redirects. Despite the fact that the HTML backend of Forester 6.0 doesn't support any customisation, I was able to inject my customisations including Gregorian chants, syntax highlighting, TSV tables and most of my style tweaks simply by making a custom Forester 6.0 theme that replaces the existing style.css with a file that @imports my additional style sheets, and similarly the min.js with a file that imports all of my custom scripts.

There were a few bugs or minor things that I had to fix, that I'll document here:

• The new search dialog looks for forest.js in the wrong place, so I hardcoded a fix for my forest in my custom theme.
• The generated pages preload katex.min.css but don't actually load it. I put a @import(katex.min.css) line into my stylesheet to fix this.
• The generated index.html redirects to the wrong place, so I put a custom index.html in the custom theme that overrides Forester's generated one.
• The top-level .block elements in a page didn't have the data-taxon attribute which my custom stylesheet depends on. I guess this is also a bug, as it's a regression from the previous Forester 5.0 pages. I added this to the Forester source code in my private fork.
• The download link meta-data that I added custom to my XSLT sheet in Forester 5.0 is now hardcoded in my private fork of Forester 6.0. Perhaps when more customisation options are added (and the above bug fixed), I will not need a private fork anymore, as this is really the only customisation I had that cannot already be accommodated by my custom theme.
