Adding a function that return user's latest reply

[edison1119]

When a user reply a decent amount of thread, fetching said user's replies will possibly get account suspend or restricted, So hereby i suggest a function that don't request for all reply or adding new restricting var (like a limiting range) to get_user_threads_replies so that it won't send out a huge request that likely raise suspection of automated account.
Also, thank you for your wonderful package :D
