Details:
Subcommands and Subcommand groups not yet implemented, they will require for some parts of the code to be re-done. More attributes can and should be implemented, such as [Required] and [Choice(... , ...)].
Breakdown:
* Rectified line endings to LF, as per the settings of the project.
* Added a new command to SlashCommandService and SlashCommandServiceHelper to register the found commands to discord.
* Implemented CommandRegistrationOptions that can be used to configure the behaviour on registration - what to do with old commands, and with commands that already exist with the same name. A default version exists and can be accessed with CommandRegistrationOptions.Default
* Modified the sample program to reflect the changes made to the SlashCommandService and to also register a new command that tests all 6 types of CommandOptions (except subcommand and subcommand group)
* At the moment all commands are registered in my test guild, because the update for global commands is not instant. See SlashCommandServiceHelper.RegisterCommands(...) or line 221.
* Modified SlashCommandInfo to parse arguments given from Interaction, unde in ExecuteAsync, and added method BuilDcommand that returns SlashCommandCreationProperties - which can be registered to Discord.
* Renamed in the sample project PingCommand.cs to DevModule.cs
* Added custom attribute Description for the command method's parameters.
* Implemented SlashParameterInfo - and extension of the OptionBuilder that implements a method name Parse - takes DataOptions and gives out a cast object to be passed to the command Delegate. Planning on doing more with it.
* Moved SlashCommandBuilder.cs to the same directory structure
* Moved SlashCommandModule.cs and ISlashCommandModule.cs to its own folder.
