Public bug reported:

Since libreoffice 4.0 is in beta stage, I think we should start looking
at supporting it in the presentation plugin.

According to the release notes
https://wiki.documentfoundation.org/ReleaseNotes/4.0

these changes could cause openlp to not work with libreoffice 4:
- "The bundled Python was upgraded from Python 2.6 to Python 3.3" - libreoffice 4 integration will probably work only with python 3
- some api changes/removals/deprecations

One solution could be to not use UNO-python but use the ctypes module
from python that is able call directly functions from C/C++ libraries.

I think that with ctypes we could support multiple libreoffice versions
without worrying about UNO and python incompatibilities.

To ease the creation of ctypes bindings for libreoffice we could look at
a tool ctypesgen that could generate pure python bindings from supplied
C/C++ headers.
