Update the picture color richness and fix the lost archive problem

1. Fix archive loss

Now there is only one automatic archive, and the format of the archive name is "date_time", For example: the archive name is 20200803_ 085503, the storage time of the archive is 8:55:3, August 3, 2020, and the "automatic archive" is added after the date "_AutoSave"

2. Add style richness to various buttons to make them look more beautiful.
