• [command_meta.if] feature: new module to provide the /IF command, which allows you to express conditional logic, such as if ... then ... else ....
• [command_meta.nop] feature: new module to provide the /nop command. (It's useful to be combined with /if command.)
• [command_debug] feature: now will send the debug info to the command source, instead of the console.
• [command_meta.chain] fix: should not continue to execute the chained commands if the previous command is only partial success. (This affects the commands like /execute if ... if ... if ... combination.)
• [cleaner] fix: should not call the clean function in async task, which may crash the server.
• [docs] fix: should display the * character in document string.
