[PC-98] JAST Memorial Collection backported english patches 1.0

These patches inject the english script of the three games (Season of the Sakura, Runaway City, Three Sisters Story) composing the JAST Memorial Collection into their original PC-98 versions.

They also include uncensored graphics for Runaway City and a new title screen for Season of the Sakura.

All games have been tested on real hardware and should run without trouble, but don't hesitate to report any bugs you encounter.
