fix(zone): lengths and counts in zone files are checked against what is left of the file

Browse Source 
A string length, the path chunk's length and an object's render technique count are
compared with the bytes left before memory is set aside for them. The terrain reader
is built into dCommon, so every server that reads zone files has it.
