New cxs v2.88

Changes:
– Include gzdecode() detection for PHP scripts
– Switched from using LWP to HTTP::Tiny to reduce memory footprint and reliance on the LWP perl module. The HTTP::Tiny module is included in the distribution, so no further action is necessary
– Modified cxs watch daemon to use POSIX::setsid()
– Modified cxs quarantine routine to reduce memory footprint
– Modified loading of Pod::Usage only if necessary to reduce memory footprint
– Modified cxs watch to not fail startup if new watch resource disappears before completion
– Exploit fingerprint definitions database additions
