Fixed path and SHA for v1.3.1 chipKIT-core release to point to correct zip file for the core. It was pointing to v1.3.0. Note that this will make no difference in a practical sense because both zip files are identical (only the compiler - a separate download - was changed between v1.3.0 and v1.3.0)
