Extend module to support other tracking codes

Hi,

First off, great module! I've overlooked this module so many times thinking "why wouldn't you just stick it in your theme". I recently had occasion to review it more deeply while building a new site and, well, now I get it!

One feature that I find very useful is the ability to exclude the tracking code for different roles. (My sites tend to be relatively low traffic b2b sites, so admin activity can really skew results.) As a result, I'd like to find a way to extend this module so that the other tracking codes my sites use (can be 2-3 per site) can be controlled by this module.

I can pretty easily hack this into the module for my own use, so that's not what I'm asking for here. Rather, I'm wondering (a) if anyone else sees a need for this, and (b) if the maintainers feel this would be appropriate for this module.

Another option would be to create a Tracking Codes module that has generic functionality for inserting and managing tracking codes, plus an API for modules like Google Analytics to register new codes. Same two questions apply.

Thanks
