Update to kyopon-0.5.
- Change "AIR-EDGE PHONE" to "PHS handset" since Willcom \ 
doesn't use the term
  any longer.
- Add support for "Photo" folder (and any unknown folders).
- Remove checking against 1.5MB limit, since new models have more capacity.
  Result of writing too large file is unknown.
- Make sure reading non-existent file on the handset will be properly warned.
- Add Linux support (but do not enable since it requires non-standard driver).
