Build 26580780

Update v1.1.2 is now live. This update fixes the screen looking frozen while saving or loading on large lines.

🛠 Improvements
・Time-consuming operations now show an indicator such as "Saving..." or "Loading..." in the middle of the screen
　This covers saving and loading (including "Resume"), saving in timetable creation (Ctrl+S, "Save and play" and so on), and saving, to-do checks and the pre-publish Workshop check in map making. Input is blocked while the indicator is shown, so pressing a button repeatedly will not run the operation twice.
・The timetable list now appears right away after you pick a line on the title screen
　On large lines, it used to take several seconds before the list appeared. The check for mismatches between a timetable and the map (the label) now runs after the list is shown.
・Some loading of large maps and timetables is now faster

🚦 Fixes
・Fixed Ctrl+S sometimes not quicksaving if the Save/Load window had never been opened
・You are now notified when saving or loading fails (previously nothing was shown in some cases)
・Fixed pressing keys such as Space during saving or loading sometimes releasing the pause right after loading

📝 Notes
・Quicksave (Ctrl+S) is not available while fast-forwarding, or while the "previous save" prompt is shown at startup.

We will keep making improvements and fixes. Your feedback and reports are always welcome.
