[O] PATCH -- allow user to set minted style

[Michael Weylandt]

Here's a small patch which allows the user to set the Minted highlighting style 
for latex export. 

This requires a different mechanism than org-latex-minted-options since it's a 
global/preamble option. 

Apologies for the badly formatted patch. I'm not at my own computer and wanted 
to give Bastien a chance to include it in 8.2.6. I do not have FSF papers 
signed but I believe this falls under the TINYCHANGE rule. 

Patch applies against a6485af3.
