Re: [O] Location of OpenDocument style files should be configurable

Makefile in org-7.8.02 is buggy and breaks the ODT exporter. Bastien, is
 likely to re-publish a version of org-7.8.x soon.

Lately, there has been some confusion around how and where OpenDocument
style files go. There have also been multiple bug reports surrounding
broken export.

Org-7.8.x has been accepted in to Emacs-24.1 [1]. I have proposed that
the style files go as "c:/Program Files/emacs-24.0.92/etc/org/*.xml"
[2]. Note that under stock Emacs, the org package go under "org" subdir.

(locate-library "org.elc") => "c:/Program Files/emacs-24.0.92/lisp/org/org.elc"

So, will it be acceptable, if org-odt.el searches for styles file under
<wherever-org-odt.elc-is>/../../etc/org/. (For vanilla Emacs, this is
same as `data-directory'/etc/org. See C-h v data-directory)

This way the package structure under gentoo will parallel the structure
under stock Emacs.

I am copying Sebastien (the debian maintainer) and Dave (who fixed the
Makefile subsequent to 7.8.02) release. If there is consensus, I will
fix org-odt.el and also Makefile.

Side Note: I am little bit hesitant to make org-odt-styles-dir a
defcustom. Already there are defcustoms for org-export-odt-styles-file
and org-export-odt-content-template-file and making org-odt-styles-dir
will add needless confusion to the users.
