dwl added an "appid" field as output status [1]. We currently don't
handle this field, and thus output warnings that say "UNKNOWN action".
Handle the "appid" field correctly and expose a value of this field to
users. Also, suppress the warnings.

Uupdate the title when process a new batch of info instead of call
strtok_r and looping until `string` is NULL.
This fixes an issue where only the last part of the title was kept.
