Release Name: niak "boss" version 0.12.16 -- pre-release -- unstable

This is an unstable, pre-release version, including mostly bug fixes.

* main feature is a bug fix in the BH FDR procedure. The procedure was too conservative before the fix.
* the default FDR method in the GLM pipelines (connectome and FIR) is now BH, not group-FDR, which seem to be too liberal in a number of situations.
