Remove unused vars, convert tug_crate arg to table
The tug_crate conversion is for performance. `foreach(tbl, predefined_func)` is substantially faster than a standard `for` loop using the `all` iterator. However, if the function inside the foreach is defined inline, it's much slower due to closure-construction overhead (even though nothing is being closed over). Converting `tug_crate` to take a table as an argument allows foreach to feed right into it, and it also naturally suggests a rewrite a few lines down to get rid of duplicative listing of `mx0,my0,dmx,dmy`, saving several tokens.
I'm going to take a look at can_move to see if it's worth making iits mx0,my0,dmx,dmy arguments into a table as well.
can_move also takes a rope operation table
this is approximately token-neutral but performance-saving. each function parameter makes its call cost worse. When can_move is called inside a loop, we already have a table and we unpack to call can_move; moving the unpack into can_move saves us marshalling cost. It requires us to construct a table in a different spot (where we were not previously doing so) but that spot is not in a loop.
calc_push op loop golf
Reorganizing conditionals saves tokens here.
Fix syntax errors.
This also saves a few tokens and cycles by turning level:tug_crate into a free function. It's not _pretty_ but it's the least bad option.
_calc_push golf redux
Removed unnecessary variable declarations and conditional cases by using an "assume, alternate, verify assumption" pattern and reusing ax0/ay0 when they would never be referenced again.
Fix syntax errors.
Slightly more efficient fix to level_tug_crate.

Save/load system. Not golfed.
Saves the music flag, the last level the player played, and the furthest level reached. Loads music flag on launch. Title screen starts on most recent level played; when in "release configuration" the title screen will only let the player pick levels up to the maximum reached through gameplay, but right now this is replaced with the 31.
Save file can be wiped by holding the down arrow at the title screen.
block writes while reading
Disabling writes during "wipe" and "first load" is not quite semantically what we want, it's writes during read we want to block. This happens because turning the music on or off tries to save the state, and it's easier to just ignore that persistence request than to rework the music code so it doesn't. "wipe" and "first load" are when we're actually reading (and enacting) state, but it's the act of reading rather than those two acts that should block writes.
It is also unwilling to write until it's done its first read, which I think is a feature; it makes it harder to accidentally blank out the player's data.
Show blocked moves as an animated X.
I am not convinced the sprite is very good. This could help the player learn what pulls were considered before proposing the ones that would occur if the player pulled the tongue. Or it's just visual noise that sucks. Anyway, this correctly captures what the blocked considered moves were, and we can decide whether to use it or not.

Debug mouse is now its own module, so it can be separated from the hint system, since it is useful for more than just positioning hints. It now has the following enhancements:
1. Clock-based table cyclng now has a helper function (cycle)
2. Debug mouse color cycling is distinct from hint color cycling, so debug position readout remains legible
3. Debug position readout now stays on screen even when the cursor is near or past the edges
4. Debug cursor cycles between a mouse sprite specifically marking the exact pixel that is being sampled, an "X" for text character sizing, and a "□" for positioning the centered 3x3 characters often used as hint target markers
5. Map cell coordinates (in square brackets) are displayed in addition to pixel coordnates (in parentheses)
Sprite 50 is now the mouse cursor. Color 15 is color cycling for debug readouts.
Debug mouse features can be disabled by commenting out `add(real_modules, debugmouse)`.
I've done a little bit of golfing but this is stiill a token expense. I'm going to write a crappy sprintf function to save tokens everywhere we're assembling strings from their component parts.
Simplify debug info display.
Save tokens by omitting parentheses and map coordinates. Adjust location to match.
Instead of cycling between symbols, the cursor shape can be chosen by using left, right, or both mouse buttons.
