Update to version 0.2.0

Bugs:

• Fix NULL check against lcap data from the jail which was actually setting lcap to NULL. This lines up with similar code in jexec(8). Github PR #1
• Fix compile warning and segfault if lcap was actually NULL - can't cast the jusername struct to string output Github PR #2

Enhancements:

• Support dynamic maximum number of groups rather than relying on compile-time NGROUPS Github PR #2
• Support specify target jail by jailname or jail ID through use of libjail jail_get_id() Github PR #3
• Return more specific details when username/UID mapping into jail fails Github PR #3
