It's not FIFO loading, but does the right thing in the common case:
If a vehicle is empty and another vehicle is already loading the same cargo at this station then the vehicle waits.
This is an reworked version of [ 1072211 ] submitted by Hackykid, thanks!
This includes 2 fixes
-Fix: [1048596] Monorail and Maglev sounds are swapped (r511)
-Add special case to load the jackhammer sound (r478)
The rest are cleanups und enumeration to make merging possible/easier
-Fix: Graphs now accomodate 64bit numbers (so the company value graph doesn't plummet into -... if value is too big)
-Strgen: added CURRCOMPACT64 for this, and 64bit versions of several macros.
-Fix: desync problem fixes
-Fix: server doesnt hang anymore when a client timed out
-Feature: low latency connection enhancements [*net_sync_freq, *net_ready_ahead]
except for German Townnames (also fix one typo on
English town-names)
-CodeChange: *act_paper to *act_water in Town to
more resemble its use
-Fix: AI players now retain AI status. Since TTDLX
savegame status is not fully documented, some holes
exist (AI state is set to one without a vehicle, otherwise
it crashes)
