Refactor Debug Keys
* Collect debug keys into a central location so that the debug help dialog can automatically list every defined debug key.
* Add buttons so that debug actions can be taken directly from the debug help dialog.
* Add new debug keys to immediately fight an encounter from the current outdoor section.
* debug_leave_town use same logic as normal town exit. fix#549
* Standardize all save party code paths
Fix#480Fix#204Fix#267
* remove file_in_mem now that it is redundant
* Print message when save file not chosen
Quality of life: Spellcasting
This makes changes to the spellcasting UI.
* M or P to recast will no longer default to Light or Minor Bless/Minor Heal. You need to cast something before recast becomes available. This fixes#535 and I think it's disorienting when I've just started the game and M casts Light in a town that's fully lit, so the change is generally good I'd say.
* I implemented a recasting hint in the text bar, which was one of the things I mentioned in my quality-of-life checklist https://github.com/NQNStudios/cboe/issues/16. It replaces the status icons in combat mode.
* Sometimes when my eyes glaze over, I think I'm casting the spell on the wrong side of the LED. I thought there was a bug when I cast Long Light instead of Dumbfound (even though I know the distance between the two is pretty large -- I wasn't paying much attention). I thought it would be nice to highlight the name of the selected spell. Light green seemed to make more sense than red for that, because the LED turns green. Then I made the caster/target selection texts also use light green instead of red, to match. Uncastable spells are grey.
Scenedit Quality of life: be helpful when scrolling past boundaries
I've implemented 2 features here:
* When scrolling past the boundaries of the current outdoor section, you will get a yes/no prompt which can load the adjacent section for you at the corresponding center position.
* When scrolling past the boundaries (literal, not the changeable rectangle) of the current town, the editor will ask if you want to jump to the town's entrance in the outdoors. If there are more than one, you can choose.
I did this because I need to be able to find town entrances in the built-in scenarios so I can debug things.
This makes it so arrow keys/numpad can control screen shift when it's available.
When this preference is enabled, #482 will not be an issue (Fix#482). But the player will also miss out on cases where adjacent targeting would be a good thing. I haven't done anything smart to determine whether one mode or the other is better on a case-by-case basis.
This fixes#489.
I considered an alternate solution of adding a case for every 1-sq-target spell, but there are so many of them. Targeting 1 square is a sensible default, not something that should have to be specified, and this warning would only really be useful when adding new spells to avoid forgetting to specify their shape. I say we don't need it.
Fixing text buffer texture/font corruption (#479)
* #479 demonstrates that the contents of the text buffer are NOT irrelevant for reproducing bugs. So I set up recording/replay for the burma shave easter egg. This also makes an easy way to mess with the buffer state when debugging (just mash &/\*/&/\*/&/\* n times)
* When a replay throws an error, it puts up a showError() dialog. If the next action is a control_click, the system will try to click that control on the error dialog--which is totally divergent from the replay's intended behavior. So we should just stop replaying when an error happens.
* If you have a long replay and want to run it very fast, but then slow down when you get to the sequence that reproduces your bug, now you can add a `<change_fps>` to your replay to achieve that.
* Fixes for the 2 legacy replay errors that I opened recently
