RATIONAL tags are defined as a ratio of two LONG, themselves defined as
32-bit unsigned integers. The value is misinterpreted when converting to
an int, double or string, as the numerator and the denominator are
interpreted as signed values. The problem has been noticed with the
ExposureTime tag generated by libtiff, which sets the denominator to
0xffffffff for exposure times lower than 1. Fix it.

- BOM is now checked and correctly handled
- auto-detection of UTF-8 string if no BOM available, otherwise assume
it's an UCS-2/UTF-16 string
- try to autodetect endianess of UTF-16 string by counting zeros
- possibility to enable writing BOM for this field (disabled for now)
- for undefined charset (empty identifier), RT now assume that the
string is what glib think is the local charset (not tested), and try to
convert it to UTF-8 for display/editing
JIS is still not handled though.
1. RT could crash in some circumstances with single frame image
2. UNICODE UserComment now done when already existing in raw file
3. When editing UserComment in the ExifPanel, the Value filed is now
filled with the current value
- CIECam now gets the shot's setting of the selected frame
- 'UserComment' metadata now correctly handled
- RT prepared to handle XTrans multiframe
- SensorType now set in the cache/data files
- Exif of all frames are displayed in the Editor's Exif tab (without
separator)
- isHDR and isPixelShift is added to the data files stored in cache
- In the Editor panel, the QuickInfo frame display the HDR and
PixelShift information, as well as the number of frame and bit-depth for
HDR image
- the number of frame is provided by dcraw. If not set, it is provided
by the Exif's main IFD count
- the PixelShift information (for Pentax as of now) is provided by
looking at the Exif informations
- the HDR information is provided by the Exif information of the first
frame for Pentax raw files, or by the bitspersample, sampleformat and
compression tags for other files
TODO: add icons to the thumbnails to tag HDR and PixelShift files.
