[O] ox-bibtex: Allow for missing bibtex style

[Julian Gehring]

Hi,

I recently started using ox-bibtex, and was impressed by the nice and 
simple functionality.

Currently, it is required to specify a bibtex style when defining the 
bibliography:

#+BIBLIOGRAPHY: bibfilebasename stylename optional-options

Would it be reasonable to allow for a missing 'stylename'?  Such that if 
'stylename' is missing or 'nil', that:
a) 'stylename' is passed with the '-s' argument to 'bibtex2html' and
b) the line '\bibliographystyle{stylename}' is not added to the latex 
output?  Then, the bibtex style can be overwritten by default settings 
of the latex document.  At the moment, this results in a warning about 
two conflicting styles.

Would be happy to hear your opinion about this suggestion.

Best wishes
Julian
