Checking ratio of the compression

[sp0ng3Bob]

Hi.

PROBLEM:

Sometimes the compression doesn't actually do much and the ratio percentage is negative.

SOLUTION:

I added a simple if to check whether the ratio is negative and if so returning False from the compress function and aborting the end process with an exit code 2.

Cheers, B0b

Negative ratio means compression is worst, so we should keep it
