Flight 4.2.0

Fixes

• Map float to double internally to support Float type parameters in commands for slash commands.

Additions

• Crude support for autocomplete on parameters using @Autocomplete("nameOfAutocompleteMethod")
• Rudimentary support for pre-defined choices on arguments.
• Added guildOnly boolean to @SubCommand
  • This boolean isn't synced with Discord at the time of writing due to limitations with slash commands. Only top-level commands can be flagged as guild-only, so this is implemented as a client-side check.

Changes

• Changed SlashContext#respond0 to always return a value, which carries over to public calling functions.
• Argument#parameter is now a public field.
• Deprecated BadArgument#original in favour of Throwable#cause
• Changed ObjectStorage to extend MutableMap to improve usability.
• Changed RoleParser to allow specifying the @everyone role without pinging.
  • Users may write "everyone" to trigger this behaviour.
