Support Photos in RasterImage template

Browse Source 
Actually photos (i.e. .jpg files) where supported previously, but for pdflatex
output an unneeded conversion to png was done. The RasterImage templates
behaves now exactly as InsetGraphics for these files: If the input format is
jpg, use that for pdflatex, else convert to png.

This is useful to avoid uneeded conversions for output formats that support
both PNG and JPEG fomats.
The predefined RasterImage template uses this macro for the PDFLATeX output
format.

HelpText
A bitmap file.
Use this template to include bitmap images of any kind except
photos in JPEG format: These will be uncompressed by this
template, therefore it is better to include them with a
graphics inset, since the graphics inset preserves the
compression if the pdflatex compiler is used.
Use this template to include bitmap images of any kind.
