0.5.27

More performance + correctness bugfixes.

• The parser has been made a little more robust to prevent major indexing issues (or at least recover from them
  quickly).
• Several new strange tag variants are now supported.
• Markdown links are now properly indexed again.

Some DataviewJS performance issues should be resolved now, especially for external plugins using Dataview. This fix
does involve a slight API break w.r.t. what types are wrapped into Dataview Arrays (which provide functions like
.where()). Generally, only Dataview-provided implicits are wrapped in data arrays now; frontmatter and inline fields
are always now regular JS arrays - use dv.array() to explicitly make a data array if you want the advanced querying.
