#335: Private threads hotfix.

#!components: grid-bot

ExecuteScript.cs:
~ Take reference to current DiscordShardedClient.
~ Move correspondence calls when errors are called to use LuaError instead of regular follow ups.
~ Add detection of scripts containing code blocks within zero content (causes exception)
~ Rewrite error for scripts that contain unicode to reduce ambiguity.
~ Rename GridJob to ClientJob.
~ Clean up call to PollDeletion
~ Integrate use of GetChannelAsString and GetGuild.

OnSlashCommand, OnSlashCommandExecuted, LoggerFactory, ScriptLogger:
~ Clean up usings.
~ Rewrite GetGuildId to use extension methods.
~ Change around references to channel to use extension methods.
