- Fix wrong RGB channel order if image format is other than (A)RGB32
- Write right resolution
- Set right resolution on image load
- Return false on write error
- Save images with depth greater than 24-bits
(cherry picked from commit e60dfd4968)
They were already disabled when building with Qt >= 5.3 in commit
3d45b270ea because Qt has better plugins
for those image formats. Now that we depend on Qt 5.3 we can remove
them.

It now uses QDataStream to deal with endianness. It also supports
several QImageIOHandler options.
This comes with a more comprehensive test suite than the old code. Note
that the old test suite was incorrect as the old code wrote the floats
in the header out incorrectly (although no-one noticed because no
software seems to care about those values).
All the test PIC files in the test suite appear correct according to the
specification (by inspection with Okteta). Unfortunately, there is a
lack of other freely-available software that reads and writes PIC files
(the main application that uses them is proprietary), and so this is the
best I can do.

Two main tests: read the file and compare to a given image (loaded from
png), and write a file out and compare to a previously-written image.
The write test in particular is kind of fragile, but it should help
catch some errors where a code change was not intended to affect the
output of the plugin.
Tests are included for all the writable formats, as well as every
readable format that GIMP can write to (and so I could easily get an
example of).
