corrected KeePass functionality now that -d works

because the external function doesn't immediately exit, we need to wrap
the eval to capture the password then return the password at the end of
the keepass function.

This also renames conn() to control_loop()
added test for if debug on when we use load_syntax
autocmds added to dottelrc.testing

We'll test these and other user supplied commands sent through a
loopback router if we ever get the loopback testing stable.
this may fix the out-of-order issues

I don't like this fix but the combination of \n after password and
suppressing output seems to have stopped failures on my test box.  I've
run it 86000 times without failure.
bumping version for test release to CPAN
