Review Request 128283: Add checksums tab to the properties dialog

[Jaroslaw Staniek]

readAll() is problematic, why to potentially fill all the ram completely,
thus removing cache?
Such approaches can degrade overall plasma's performance.

can retrieve and verify the most popular checksum algorithms (md5, sha1 and
sha256).

user opens the dialog. This can take a while if the file is huge (in
particular with sha256), but the computation happens in another thread and
in practice this should not be a performance problem.
