0.2.0

Added

Lua values may now be set to functions that will return the desired type. This prevents code being run multiple times when multiple Lua VMs are spawned.
The watch function has been added as a builtin helper function for executing a shell command and following the output. The function takes a shell command as the first arg, and optionally a value to use if the command fails to start.
When built with the unsafe feature flag, the --safe flag can be passed to the command line to only load safe libraries anyway.
The --dry-run command line flag can be passed to prevent attempting to connect to Discord.
Fish and Zsh completions are now provided with the release.
Systemd, Runit, and OpenRC template services can be found in the etc directory.

ClientID has been renamed to ApplicationID to better reflect Discord's own usage and reduce ambiguity.
Output has been cleaned up, making use of simplelog.
Command help text has been improved.

The output binary is now named disco. Previously it was mistakenly called disco-rpc by default.
