Separates the 'count and assess everything' stuff to it's own datum, called the metric datum, which I plan to add on to in the future to make counting and metrics easier.
Makes decision process a bit more weight-based, will probably continue tweaking later.
Makes the admin debug UI have links to change settings easily.
Adds replacement for grid check event, which works similar to the old one, but is now based on a physical machine in the game world, that Engineering can hack to make the event end faster, if so desired. Note that the machine is not mapped in, and won't be mapped in until the event system is ready for launch.
Adds grid_check variables to SMESes and APCs to make them stop doing work without draining the battery.
Grid checks in the new system are caused by a "power spike" which originates from the engine and will cause bad things, should no grid checker machine be connected to the power-net. These power spikes occur when the GM decides that a grid check is a good event to have.
The grid checker can be built and deconstructed using the standard machine construction methods.
Ports PsiOmegaDelta's port of integrated circuits, which has several improvements in code quality.
Ports a few small things like the weakref datum and some macros.
A lot of new defines are now in inventory_sizes.dm, which contains;
All the size identifiers (the thing that tells the game if something is bulky, or w/e).
Storage costs for all the sizes, which are exponents of two, as previously.
A few constants for inventory size.
Also changes all storage item's capacity definitions by basing it off of how many 'normal slots' exist for it. This allows one to change the definition for all of the defines in the file, and everything will follow along without needing to change 500 files. In testing, I made all ITEMSIZE_COST_* defines doubled, and nothing had broke.
The benefit of doing all of this is that it makes adding new weight classes in the future much simpler, and makes knowing how much space a container has easier, as seeing ITEMSIZE_COST_NORMAL * 7 means it can hold seven normal items.
