Updated to 2013_sp1_update1.

Also removed requirement to have a license file in ${basedir}, since users may
wish to place their license files in ~/intel/licenses, or manage licenses
out-of-package.  This also means the package can be installed with yaourt now:

    yaourt -S intel-parallel-studio-xe

HOWEVER, if using yaourt, remember to set your TMPDIR to something other than
/tmp since the package downloaded consumes 3.2GB of space.
