commands: allow printing raw properties 

Extend m_properties_expand_string() so that it can print properties as
unformatted string. Normally, properties will be pretty-printed
(intended for OSD and user interface purposes). Add the '=' modifier to
the format string syntax that disables pretty-printing and returns them
"raw".

For example, "${=switch_audio}" will print the track number, instead of
returning an OSD friendly string containing additional information like
track title and language.
