Added check to BaseImporter::SearchFileHeaderForToken making sure that a detected token is not in fact just a fraction of a longer token. Microsoft exported binary gltf files were detected as OBJ, because the "gltf " in the string "Microsoft GLTF Exporter 2.4.1.7" was detected as the token "f ". I added a new bool parameter to the method enabling this check. It's default false, and only ObjFileImporter sets it to true, so no other code should be affected.

Remove assertion in ObjFileImporter
...
This assertion is already handled by an exception, and could lead to a
crash when parsing an ill-formed OBJ file.

Fix buffer overflow in obj loader
...
The overflow-checking code in ObjFileImporter::createVertexArray is at
the wrong position, allowing buffer overflows in preceding code.
This fix moves the code to the right spot.
An actual overflow can be caused by usign some more bugs and weird
behaviours and injecting a malformed line statement into the object
file, containing only one index. Such a malformed file could for
example look like:
o 1
v 0 0 0
v 1 1 1
v 2 2 2
l 1
f 1 2 3
Because the code in ObjFileImporter::createTopology incorrectly handles
line-type faces containing only one index (in line 364), it
underestimates the number of required indices and therefore causes the
buffer allocated in line 421 to be too small.
I believe, the correct fix for this would be in the parser and
rejecting such faces early. However the overflow check was misplaced
anyway.
If you can't reproduce a crash, just insert some more "l 1" lines
before the "f 1 2 3" line until it crashes. The behaviour of heap buffer
overflows strongly depends on memory layout and allocation history.

ObjFileParser: Moved the parsing of line continuations (backslashes) to the parsing code.
...
Rather than removing all backslashes followed by newlines from the buffer,
and then parsing it. Handle removing the backslashes as we go. This means
we don't need to erase the backslashes from the buffer (which is O(n))
instead we just skip those characters as we parse the buffer line by line.
This time I've fixed the order of evaluation bug in the call to getFace().
