Add a function concerning RE Textures

[Olganix]

There is a second use of "Load textureblock" "sub_42D680(3);"
-the first is on Load Model function, because model and Textures are linked.
-the second is on a function witch
-read 4 bytes for cheaking (xx < 1700), else it's a infinity loop.
-copy 0x1A90u bytes in a global variable.

Pretty sure you are talking about this (patched US version):

//----- (00447420) --------------------------------------------------------
void sub_447420() {

  // Open textureblock
  sub_42D680(3);

  // Read 4 bytes from the textureblock and swap it; this is the number of textures
  sub_42D640(3, 0, &dword_E9823C, 4u);
  dword_E9823C = swap32(dword_E9823C);

  // Ensure that we have 1700 or less textures, hang otherwise
  if (dword_E9823C > 1700) {
    while(1);
  }

  //FIXME: Unknown
  // Global variable: `int32_t dword_E93860[1700];` - Texture pointers probably?
  memset(dword_E93860, 0, sizeof(dword_E93860));

  // Close the textureblock again
  sub_42D6F0(3);

  return;
}

Someone should verify or redo my work and send a PR.
