Simplify some WriteBlockAtOffset() calls.
These IFX_SeekableStream::WriteBlockAtOffset() calls can be simplified
to just calling WriteBlock(), since they only happen when:
- A stream has just been created, and the offset is 0.
- When the offset is the end, which is what WriteBlock() does.
In turn, WriteBlock() simplifies to WriteString() in most places.
