Cosa è cambiato in EDuke32, build per build

Fix addlogvar command, broken in r5835.

Allow gamestartup to read in one additional parameter (MAXFLAMETHROWERAMMO). Do nothing with it yet.

Implement "ifplaybackon" conditional, used by World Tour to determine if the replay feature is enabled. In our case, it is always false.

Add getpv and setpv as short forms for get/setplayervar, and #include as an alternate for include.

Add ifvarge, ifvarle, and ifvarboth in line with ifvarvarge, ifvarvarle, and ifvarvarboth.

Fix the return command within events, broken since r5097.

Clean up pointer handling in the parser so we have less to re-offset in C_SetScriptSize. Also fixes bugs in r5093 and/or r5097.

Fix VM_ScriptInfo so that it never reads before the beginning of the bytecode.
