Released a new version of idmclib

A new version of the idmclib (version 0.8.0) have just been released. You can grab it from the usual place.
This new version now depends on GSL version >= 1.9 (instead of 1.7).
This version of the GSL library finally have functions for the computation of eigenvalues of real nonsymmetric matrices. This frees idmclib from the need of Fortran LAPACK code for this specific task.

So, what does this means in practice?
To the end user of the idmclib library, nothing, except that now a different algorithm is used for jacobian eigenvalues computation in the periodic cycles routine.
For anyone who wants to compile idmclib on his platform, means that you don't need a fortran compiler anymore: CMake + gcc will be enough!

This change should facilitate redistribution of idmclib, and its use in other projects.
I'm already working on upgrading RiDMC to this new version of the idmclib. Then will be the turn of the stand-alone iDMC.
