Version 1.12-0.5.0

Changes:
* When submitting CBOR to a syscall, binary-encoded UUIDs stored as byte
  strings can now be tagged with tag 37 (UUID), which is more correct
  than tag 39 (Identifier). Tag 39 is still supported for backwards
  compatibility, but tag 37 is preferred.
* When submitting CBOR to a syscall, Unicode strings and byte strings
  can now be stored out-of-line and referenced via a small descriptor
  tagged with the tag 32,769 (External Reference).
* A configuration option is added which causes a stack trace to be
  written to the Minecraft debug log when a syscall fails.

Fixes:
* Unallocated and reserved CBOR simple values (i.e. major 7 values 0
  through 19, 28 through 30, and 32 through 255) now cause a CBOR decode
  error rather than being interpreted as `null`.

Version 1.12-0.4.0

Changes:
* The `computer` module contains a new syscall `debug`, which, when
  enabled in the mod configuration, writes a message to the Minecraft
  debug log.

Fixes:
* CBOR numbers larger than 32 bits are now supported, being decoded to
  Java `Long` objects.

Version 1.12-0.3.0

Changes:
* The `component` module contains two new syscalls,
  `lastExceptionMessage` and `lastExceptionIsType`, which allow getting
  more details in the event that a component method call ends with
  `BAD_PARAMETERS` or `OTHER` error codes.

Fixes:
* Some missing information in `mcmod.info` is now filled in properly.

Version 1.12-0.2.0

Changes:
* The pullSignal system call in the computer module now encodes the
  signal as a CBOR sequence of two elements, the first being a string
  holding the signal name and the second being an array holding the
  parameters. It used to encode signals as a single array containing the
  name followed by the parameters. This makes decoding signals easier,
  as an application can decode the string, dispatch on signal name, and
  then decode the array to a typed structure as a single whole CBOR
  item.

Fixes:
* Modules that declare a maximum linear memory size no longer get 65536×
  too little memory.
* Modules that declare a maximum linear memory size greater than the
  amount of RAM installed in the computer now display a more useful
  error message.
