[O] use of 'system in ox-odt.el

[Matt Price]

Hi,

When I export-and-open to odt, org doesn't open the resultant odt, even though I get a message:

Running xdg-open /home/matt/RLG231/RLG231Syllabus.odt...done

org-open-file works fine on links in an org buffer, and an anser on the following stackoverflow page suggests the issue is in ox-odt.el:

Below is a git diff for the suggested change:

----------------------------

I'm not sure what 'system does in the changed line -- the documentation suggests a non-nil argument here will result in the odt file being opened in a buffer rather than in a browser. Nocolas, others, does this look like a bug? sorry I don't know more.
