Framsticks

Fixed fputs("") reporting an error in Android MFILE implementation

Introduced a shared function to avoid code duplication; more informative error message; frees memory in case of error

Newly introduced constant used (and fixed behavior for rarely used LOG_DEBUG messages)

Better use of LOG_level constants

Introduced a function logLevelName() to avoid potential errors, e.g. forgetting "+1" in LOG_LEVEL[level+1]

Improved comment

Fixed error messages, changed int to paInt (for 32/64-bit safety), changed two int variables to bool as they should be

Printfs replaced with error messages.

Nonexistent function declaration removed.

Added another, improved way of calculating dissimilarity of two creatures/models. Details and comparisons in ​https://doi.org/10.1007/978-3-030-16692-2_8

Added two methods for dictionary iteration: for(x in dict) and for(x in dict.keys)

Code formatting + cosmetic fixes

XY and XYRect for floating point values

Added files needed to compile Framsticks SDK to JavaScript? using Emscripten

Introduced a few sets of files so that the rest is more modular; SDK_LIB_OBJS now lists files for javascript SDK and related/dependent apps

Made operator precedence more javascript-like

#include <cstdlib> needed for Emscripten for malloc()

Added #include <stddef.h> needed for Emscripten

Made util-string.cpp #include util-string.h even though currently not needed, and removed unused #include

Made operator precedence more standard: conditional (?:) and logical not (!)
