Teach agent-skill consumers to capture the <sent .../> record, use
archive-id as the MAM receive cursor, avoid treating message-id as a
cursor, and fall back through recent MAM list if archive-id cannot be
resolved.

After sending a chat message, poll MAM for the archived forwarded stanza
by message id/origin-id and print a compact <sent archive-id=...
message-id=... to=.../> record. Add timeout handling so missing MAM
responses fall back without hanging, and update the agent-skill
instructions.

Add the agent-skill command and installer, password stdin/pwd-cmd

Merged 0.1 branch for Issue #26

Bugfix for checking if configuration file exists. Also did some argv
parameter checks.

Issue: #26

src/mode/roster.c:66:19: error: implicit conversion from enumeration type 'enum mode' to different enumeration type 'CommandType' (aka 'enum commandTyp') [-Werror,-Wenum-conversion]
command->type = UNKOWN;
~ ^~~~~~
Fixed by using the correct enum definition.

Issue: #21

So it will display `me@domain.org/resource: body text`.
Which is more readable to users who just want to get their MAM and not
debug things :-)

Show help if no argument is provided

In case someone calls `xmppc` assume that he doesn't know how to use it.
Which means he might even not be aware of `-h`.
So let's print the help in case no argument is provided instead of
connecting, then discoverin that no mode is selected and disconnecting
again.

Fix segfault when not roster subcommand is provided

_roster_parse_command() segfaults since it assumes there is an argv[0].
Let's test the number of arguments.

Since we are already connected xmpp_connect_client() will wait for a
disconnect. So I introduce a teardown function that is called in both
the error case and the succesful case.

Now _roster_send_query() doesn't disconnect anymore.

Set to development by default

Only set to release when a new release is tagged.
Like this not every developer needs to change the code.
And it's git aka development anyways.
