Version 1.1.13 released!

I achieved a feature that inserting header tags in table cell in v1.1.9, but this feature overwrite quill built-in header blot. Maybe it will do harm to users' webapp. So I cancelled this feature in this version. It is my fault, sorry about that. Maybe inserting headers/ul/ol in table cell will achieved in another repo, and give users a marked notice to know what should pay attention to achive these break features.
