Update the sceadan submodule.
Autoconf adjustments for using liblightgrep's pkg-config. This frees us
from having to care about ICU in configure.ac.
Updated ICU to 53.1.
* Update liblightgrep to 1.3.0 from 1.2.1.
* Add the updated ICU patches to NEEDED_FILES.
* The ICU gencode patch is not only not necessary for ICU 53.1, but is
actively harmful and causes link errors with libicudt.a and MinGW. Omit
it.
Collected common flags and defines for ICU builds.
