Output to temp file during compression, then rename after #14

When outputting to a file (and not stdout), quip should create a tempoprary file with a random name and output to that, and then once (de)compression is complete, rename the file to the desired destination. This ensures that if quip is interrupted before completion, it will not produce an incomplete output file.

Good point regarding incomplete output files. I'm more inclined to emulate standard unix compression tools (e.g., gzip, bzip2) which don't use a temporary file, but delete the incomplete output files if interrupted. I'll look into copying their signal handling logic to do the same.
