set holiday hats for nohat hogs

moon02 fixes: bug that didn't called win(), changed map so blue hog not placed on edges, teleport animations, removed amSkip, also error when drow hero and enemy seems fixed

Don't send empty theme in config

- Restrict game config changes in special rooms - /unfix command

Experiment in adding a "boing" graphic for bouncing. It has no text right now (was thinking l10n) and colour is fixed.

Add rubber utility. Graphics are still incomplete. Also flag snow/ice in theme config.

Add missing gstCollision bug #725

fix issue #724: Bee sound never stops (underwater when timer is 0) also: instead of flowers add bubbles while underwater

string/typo fixes

revert r938d1c08d0d1 in favour of putting it in the chat log. I think this addresses main concern about missing text. There've been complaints in past too about conversation in bubbles not being visible in history. If the objection is that r938d1c08d0d1 offers a more æsthetic solution, I think it should augment this, be flagged, and fix the visual issues first.

use a variable that allows negative values instead.

disallow speech bubbles to go offscreen no tint or tail-directio adjustments for indicating it's offscreen yet though

fix speechbubbles assigning negative values to a Longword value, overflowing it

It seems that at the current state it is necessary to protect sending stats/ending game from multiple execution, as that can happen if you e.g. fail a mission more than once in the same tick (e.g. destroying two essential crates at the same time) Otherwise you can get a blank / stuck frontend (e.g. when using deagle to shoot the two last crates at the same time)! the best approach might be to never call the function that sends stats and ends game from any event handler directly, but instead have a flag 'isFailed' that is set to true when any of the possible fails happen and to check that flag every tick to send stats and end game if true
