too short buffer size

[Fuzzlix]

define WBUFF 32768

reason: command lines for winapi.spawn_process() can be 32768 bytes long. If i hand over a command line string longer than this define, winapi crahes.

Wow that's seriously long for a command line ;) But yes, it's a problem since that buffer is used elsewhere. I will bump this up.
