Dirty hacks to make this compile on ubuntu 14.04 and ros indigo

[JoonasMelin]

These were the changes that I needed to make this compile and work on ubuntu 14.04 and ros indigo. The -std=c++0 needed to be removed as the PCL libraries were segfaulting with this option.
This resulted on the auto type seen in feature_adjuster to break, so it is replaced with its real type.

I also had to comment out the tf_msg->__connection_header; as it seems that it does not exist anymore (this seemd to have some proper fix on the odometry branch).

Disabling the USE_SIFT_GPU is most likely not neccessary on most systems.

Thanks for the patch! I'll need to test it on hydro before merging it because of the connection_header thing.

This is great news. We thought it would be alot more work than that to modify the code so we ended up using hydro but everything works great on our ARM board. If I have time I'll put Indigo on another drive and see if this change has any effect on our board.

Hi all,
thanks for the pull request, I now created a new indigo branch, which you can try. It's not building smoothly yet though: I needed to manually create opencv library links in /usr/lib/x86..., because of inconsisten ros dependencies and build opencv from source to get the non-free functionality.
