Use External BLAS/LAPACK by default

Check if Blas/Lapack is available and only use internal
if it isn't found

Updated FindLAPACK to 2.8.8. and included FindBLAS
so that it works without Fortran enabled.

+# - Find BLAS library
+# This module finds an installed fortran library that implements the BLAS
+# linear-algebra interface (see http://www.netlib.org/blas/).
+# The list of libraries searched for is taken
+# from the autoconf macro file, acx_blas.m4 (distributed at
+# http://ac-archive.sourceforge.net/ac-archive/acx_blas.html).
+#
+# This module sets the following variables:
+#  BLAS_FOUND - set to true if a library implementing the BLAS interface
+#    is found
+#  BLAS_LINKER_FLAGS - uncached list of required linker flags (excluding -l
+#    and -L).
+#  BLAS_LIBRARIES - uncached list of libraries (using full path name) to
+#    link against to use BLAS
+#  BLAS95_LIBRARIES - uncached list of libraries (using full path name)
+#    to link against to use BLAS95 interface
+#  BLAS95_FOUND - set to true if a library implementing the BLAS f95 interface
+#    is found
+#  BLA_STATIC  if set on this determines what kind of linkage we do (static)
+#  BLA_VENDOR  if set checks only the specified vendor, if not set checks
+#     all the possibilities
+#  BLA_F95     if set on tries to find the f95 interfaces for BLAS/LAPACK
+##########
