annotate data/fileio/DataFileReaderFactory.cpp @ 297:c022976d18e8

* Merge from sv-match-alignment branch (excluding alignment-specific document).
  - add aggregate wave model (not yet complete enough to be added as a true
    model in a layer, but there's potential)
  - add play solo mode
  - add alignment model -- unused in plain SV
  - fix two plugin leaks
  - add m3u playlist support (opens all files at once, potentially hazardous)
  - fix retrieval of pre-encoded URLs
  - add ability to resample audio files on import, so as to match rates with
    other files previously loaded; add preference for same
  - add preliminary support in transform code for range and rate of transform
    input
  - reorganise preferences dialog, move dark-background option to preferences,
    add option for temporary directory location
