COF_BUILD: added donator fields in clientdata_t and usercmd_t structures

[SmileyAG]

I don't have time to review previous requests, hope everything would be stable for me close to start of winter, but I pushed this request as a hotfix before the release.
I did it right now via the web interface instead of how I usually do it with Git CMD due to circumstances, I hope everything is OK with the commit history. DON'T EXPECT FROM ME REBASE OR SOMETHING RIGHT NOW.

If you want to know how to find these fields, I'll tell you:

• Create a delta_definition_t struct or import delta.h header in hw.dll from CoF in Ghidra/IDA Pro
• Find the DELTA_Init function, the code there will look like this:

void FUN_01d5224b(void)
{
  FUN_01d44eff(s_delta_stats_01eb399c,FUN_01d52208);
  FUN_01d44eff(s_delta_clear_01eb39a8,FUN_01d52135);
  FUN_01d51a7a(s_clientdata_t_01eb39b4,g_ClientDataDefinition,0x39);
  FUN_01d51a7a(s_weapon_data_t_01eb39c4,g_WeaponDataDefinition,0x16);
  FUN_01d51a7a(s_usercmd_t_01eb39d4,g_UsercmdDataDefinition,0x11);
  FUN_01d51a7a(s_entity_state_t_01eb39e0,g_EntityDataDefinition,0x57);
  FUN_01d51a7a(s_entity_state_player_t_01eb39f0,g_EntityDataDefinition,0x57);
  FUN_01d51a7a(s_custom_entity_state_t_01eb3a08,g_EntityDataDefinition,0x57);
  FUN_01d51a7a(s_event_t_01eb3a20,&PTR_s_entindex_01eb23b0,0xe);
  return;

• I renamed the g_ variables myself, by default you won't have it.
• But the point is that by default they will have a garbage data type for obvious reasons, but you should reassign them to delta_definition_t globalvariable[ARRAYSIZE]
• You can take the ARRAYSIZE from the last argument of the function. For example, g_ClientDataDefinition has an array size of 0x39 (57)
• Therefore, you assign delta_definition_t g_ClientDataDefinition[57].

After which you simply compare it with the data in the GoldSrc engine and make changes in your headers due to the corresponding fields.
