python/pyocr: Move package into python-modules We already have a patch feeling lonely inside the python-modules directory and to have everything at one place let's actually move pyocr into its own dedicated directory so it's easier to patch it up (which we're going to). Right now, the package fails to build because of a few test failures, so I haven't tested this apart from evaluating. Signed-off-by: aszlig <aszlig@redmoonstudios.org>

pythonPackages: Add version and pname attributes to packages

python/pyocr: 0.4.6 -> 0.4.7 Upstream changes: * Tesseract 4.00.00alpha: * Version parsing: Ignore suffix (so '4.00.00alpha' == (4, 0, 0)) * Libtesseract: Load libtesseract.so.4 instead of libtesseract.so.3 if available * Support for Tesseract 3.05.00: * Builders: Split field 'tess_conf' into 'tess_flags' and 'tess_conf' * Libtesseract: If available, use TessBaseAPIDetectOrientationScript() instead of TessBaseAPIDetectOS * Libtesseract: * Workaround: Prevents possible segfault in image_to_string() when the target language is not available Full upstream change log can be found at: https://github.com/openpaperwork/pyocr/blob/b006123d1d002711b9/ChangeLog The tesseract.patch for supporting Tesseract version 3.05.00 has been applied upstream and we can safely drop it. We now use substituteInPlace in conjunction with a patch to insert the relevant store paths instead of sed, so it's less fragile whenever we have upstream changes in handling of these paths. I've tested this by reverting 48a941e29faa95e897f and applying a build fix patch of Cuneiform 1.1.0 from Arch Linux, because right now Cuneiform is an experimental version that can't be fixed on behalf of pyocr (the reason is that pyocr needs to get a list of languages, which doesn't work in that version anymore). In addition to that I've successfully built paperwork-backend which by now is the one package which depends on pyocr. However, I didn't do runtime tests of Paperwork.
