New cxs v2.43 (security fix)

SECURITY FIX. Anyone running cxs on a DirectAdmin server should upgrade to this release immediately:Changes:

• Add check for successful open of admin.list on DA servers to avoid a segfault, which could lead to a buffer overflow

This issue is apparent on DirectAdmin servers only where this C wrapper is used.Note: cxs is not currently officially support on anything other than cPanel servers
