0.5.0

New features:

• Added Context::parent_commands()
• Added Context::invocation_string()
• Added builtins::register_in_guild() and builtins::register_globally() convenience functions
• The return value of autocomplete callbacks can be any serializable type now
• Context can now be passed directly into most serenity API functions
  • Because it now implements AsRef<Cache>, AsRef<Http>, AsRef<ShardMessenger>, and CacheHttp traits
• Added execute_modal() function with support for modal timeouts

API updates:

• Modal::create() gained a custom_id: String parameter
  • To make it possible to tell apart two modal interactions
• Removed CreateReply::reference_message(MessageReference) in favor of CreateReply::reply(bool)
  • For the unusual case of setting a different reference message than the invocation (why would you? I'm genuinely interested), you can still convert the CreateReply into serenity::CreateMessage manually via .to_prefix() and call serenity::CreateMessage's reference_message() method
• Renamed FrameworkBuilder::user_data_setup() method to setup()
• Renamed FrameworkOptions::listener field to event_handler
• Renamed Context::discord() method to serenity_context()

Behavior changes:

• register_application_commands_buttons() now has emojis, reworked wording, and prints the time taken to register
• Modal::execute() always responds to the correct modal now
• When a subcommand is invoked, all parent commands' checks are run too, now
