New Twitter DM API and function limitation of DM

We changed the DM API to a new one due to Twitter's API change.
The following limitation is caused by the influence.

1. Only DM for the past 30 days can be acquired
2. After DM transmission, a few minutes lag occurs until it can be acquired

We are sorry for the inconvenience, but these restrictions are done by Twitter and can not be improved.
Please be appreciated.
