Implemented ability to show particle effects.
Paramaterized constants and ItemTable tests.
Switched to Lombok for message classes.

Lombok automatically generates constructors, getters, hashCode, equals,
and toString methods on the annotated classes at compile time. These can
be overridden where necessary. This should reduce maintenance load on the
message classes.
Added networking unit tests.

Protocol test functionality and style fixes.
Added proxy support (fixes #114). Thanks @Johni0702!

Proxies such as BungeeCord have the option to forward the real address,
UUID, and properties from the auth process to the backing server so that
they can appear to be in online mode even if they are not.
Minor style fixes.
Fixed support for 1.8's string-based item ids.
Convert data types during server.properties migration (fixes #392).
Added player visibility API (closes #121).

Players are hidden fron another player's tab list and entity updates.
Also renamed other canSee methods to canSeeChunk and canSeeEntity.
Removed TextWrapper in favor of the client word-wrapping.

Formatting is still a little awkward. When new-style formatting is added
the old-style formatting can be properly converted, fixing any weirdness.
Checkstyle additions and matching style fix.
Show entity held item and equipment to players (fixes #164).
Added query support (closes #377).
Interpret world seed as number if possible (fixes #427).
Fetch UUIDs from Mojang if needed (fixes #227, fixes #365).

UUIDs are only fetched if online mode or proxy support is enabled.
Additionally fixes problems when player data files are missing a last
known username.
Fixed or added several broken inventories.

Added GlowInventory#getRawSlots() to handle a protocol special case.
Changed TEContainer to take an inventory rather than an inventory type.
Adds or fixes enchantment tables, anvils, brewing stands, furnaces,
workbenches, dispensers, droppers, and hoppers.
Added ender portal support (see #325).

Adds awardAchievement variant which only awards the achievement if its
parent has already been awarded. Fixes some desyncs with world switching.
Implemented basic damage functionality, including drowning.
Fixed color wrapping by converting flat messages to json.
