[O] Chose where latex preview images are placed

[Abdó Roig-Maranges]

Hi,

I'm a regular org-mode user. I have made a couple of small tweaks to
org-mode that may be useful to someone else.

In this mail I attach a patch for the first one. It adds a configuration
variable to chose where latex preview stores the little png images of
formulas. I prefer having all of them together rather than scattered all
over the place.
