fixes:
* Switching between games does not immediately hide creative mode / damage buttons if so specified
* World creation menu has a game selection list even though the menu already provides a gamebar
* Showing gameid in world list is unnecessary
* Choice of mapgen parameters in menu persists between games (and was half-broken)
It's likely that these could be used trick mods into revealing the insecure
environment even if they do everything right (which is already hard enough).
This ensures that no overflows (side-effects) happen within the find_nodes_in_area function by limiting coordinates like done in the map generation code.
This commit deprecates the forward, backward, left, and right binary
inputs currently used for player movement in the PlayerControl struct.
In their place, it adds the movement_speed and movement_direction
values, which represents the player movement is a polar coordinate
system.
movement_speed is a scalar from 0.0 to 1.0. movement_direction is
an angle from 0 to +-Pi:
FWD
0
_
LFT / \ RGT
-Pi/2 | | +Pi/2
\_/
+-Pi
BCK
Boolean movement bits will still be set for server telegrams and
Lua script invocations to provide full backward compatibility.
When generating these values from an analog input, a direction is
considered active when it is 22.5 degrees away from either
orthogonal axis.

Some games provide users with enough freedom to create items
with metadata longer than 64KB, preventing this from causing
issues is on them but we'll still do the minimum not to abort
the server if this happens.
* Add a simple PNG image encoder with Lua API
Add ColorSpec to RGBA converter
Make a safety wrapper for the encoder

Add API for mods to hook liquid transformation events
Without this API, there is no reliable way for mods to be
notified when liquid transform modifies nodes and mods are
forced to poll for changes. This allows mods to detect
changes to flowing liquid nodes and liquid renewal using
event-driven logic.
Fixes list clearing for inv:set_list() using same size, since 2db6b07.
addList() now clears the list in all cases. Use setSize() to resize without clearing.
