Keep the cloudooo revision fix to prevent inconsistent test result outcomes
during the cloudooo development. This revision adopted is the same as last
stable report for erp5 and cloudooo test reports.

This file is used by cloudooo and erp5 setup. For not they are not
compatible yet.

pdftk and dirname are required by CloudOOo.

By using cloudooo directly from git we do not use fixed versions anymore.

Install cloudooo from git mainstream (like erp5) instead rely on
eggs for this. This makes development and testing faster by adoptiong
mainstream always.

Unify the standalone setup and the setup into erp5 to provide the same
outcome and reduce maintenace.

Update cloudooo configuration to make it compatible with erp5testnode and
permit re-enable continuous integration.

env-PATH is required for use imagemagick, ffmpeg from the instance itself,
and also important to make the tests works.

The slapos default configuration decision:
- text/html does not have Last-Modified
  Because we can not calculate proper last-modified date when the page consists
  of several parts. (e.g.: Gadgets)
- resouces have 'Cache-Control: public'
  Because several versions of Firefox request 'public' to cache resources
  over SSL.
So web_checker.cfg respects the slapos default configuration decision.

No local commit is supposed to exist.

It's necessary on some platforms so it doesn't find the system zlib, even though it doesn't depend on zlib directly.

It's not necessary and was finding system X11 libraries it shouldn't touch.

update md5sum of clarified patch

Seems like old compilers need some help with indirect dependencies of libraries.

We need to remove the BOM because old compilers choke on it (ex.: gcc 4.3.4)

tesseract-eng-traineddata now does all the work

Remove deleted part from erp5 stack as well

Fix broken autoconf invocation

Use a trained data tarbal containing the correct datarootdir structure and the English data.

Instead of using the provided script. Otherwise it'll desperately try to use libtool and its autoconf macros from the system.
