Title: New masking strategy: Background mask

Most often, the compute_epi_mask is not a good strategy to implement a masking heuristic on the data that people use in nilearn, as it is not raw EPI data, but things like beta maps.

This implements a new strategy that uses the border of the image to compute a masking value.
