If multiple namespaces are present, suggestions will first suggest a
namespace, then once a namespace is selected, keys within that namespace.
Starting an argument with ":" will instead search across all namespaces
for matching keys.
Later registered parsers will always come before the default, ensuring
that the default parser is used when no other parser can match the input,
and that errors may be thrown by it to signify the end of the line.
All patterns now have suggestions, including recursive patterns.
Suggestions will suggest blocks and block states.
All masks now have suggestions, though mask intersections are not
yet supported due to issues with quotes strings.
EntityRemover and ItemFactory now also have completions, as well
as all RegistryConverters (though I am unsure how many are actually
used).
Also use paper's AsyncTabComplete event, if available.
Allows setting a mask used for block traces. This allows brush tools to
pass through various materials, such as water (e.g. `/tracemask #solid`
or `/tracemask !air,water`) before starting to build.
By default, a null mask is equivalent to #existing (original behavior).

Legacy mapper now uses the data fixers to upgrade blocks and item types
(e.g. signs, dyes that changed names in 1.14).
The sponge schematic reader can now attempt to use the data fixers to
upgrade blocks, block entities, biomes and entities. This has been
tested with the 1.13 -> 1.14 changes. It is yet to be seen if it will
continue to work because...
The mc edit schematic reader has code for using data fixers, but it is
currently disabled as there seem to be some issues with fixing up older
block entities.
Closes a few old youtrack issues which I don't remember because I had
like 30 tabs open, and a few other issues which I found while testing
some of those.
