Description
-------

Add imagedump: a utility to dump the raw data of a QImage

This is intended as an aid when writing and debugging imageformat
plugins.  It creates a file containing the bytes of QImage::bits(),
which can then be viewed in Okteta.

Diff: https://git.reviewboard.kde.org/r/116532/diff/


Testing
-------

Builds.

Tested commands:
imagedump -h (prints help)
imagedump -p (prints expected list of QImage::Format options)
imagedump -l (prints expected list of QImageReader formats)
imagedump something.xcf something.data (dumps data in ARGB32 format)
imagedump something.png something.data (dumps data in ARGB32 format)
imagedump -q RGB32 something.xcf something.data (dumps data in RGB32 format)

All data dumps sanity-checked in Okteta.


Thanks,

Alex Merry
