Parses a signal description from signal_desc and incorporates it into binding_set.
Signal descriptions may either bind a key combination to one or more signals:
bind "key" {
"signalname" (param, ...)
...
}
Or they may also unbind a key combination:
unbind "key"
Key combinations must be in a format that can be parsed by accelerator_parse.
