added working implementation of gunzip_stream()
hooked gunzip_stream() into read_file()
gzip module is unused. ha!
updated test to only allow streaming of gzipped data, refactored read_file()
read_file() now always chunks by lines, don't need this
fix boto classname in comment
implement read in mockboto's MockKey
added test of gzipped data catted from S3
moved compression in tests into utility module
added bz2 test for s3 fs too
don't make everyone pay a performance penalty just because boto.s3.Key
doesn't behave like a proper file object
make test names more consistent
added tests for Hadoop FS (test for gz fails)
fixed gzip decompression for hadoop fs
added test for SSH fs (which just dumps the file into memory)
updated copyright notices
add tomhennigan to __credits__, for his example gunzip_stream() code
on Issue #669.
namey things (which are never inconsequential!)
Merge pull request #720 from davidmarin/gunzip_stream

Make runner.fs.cat() decompress gzipped/bzipped data
