Trying to release the 0.2 official version tomorrow

Based on the 0.2 beta version, some free events have been added. As well as the rename function, some UI changes, and of course some bug fixes.

It was originally expected to add some stories about Emma in the official version, now, they will be added to 0.2.5.

The next update will be about a 20-day work, and I try to do the update more frequently.
