Add security/kpcli

Hi guys, I'm adding the kpcli utility (http://kpcli.sourceforge.net/) - it's a command line password manager compatible with KeePass 1.x and 2.x database formats.
The 2.x format is not supported by the latest stable KeePassX version (0.4.3) which is there in ports, and KeePass2 (the Mono app) hasn't been ported yet either.
