[patch] shells/fish compiler error fix, version update

[William MacKay]

The shells/fish port has failed to build on FreeBSD 10 for several 
weeks.  It fails with errors like:

./io.h:12:12: error: no member named 'tr1' in namespace 'std'
./io.h:183:39: error: no template named 'shared_ptr'; did you mean 
'std::shared_ptr'?

This patch fixes the error by telling the compiler to use C++11.  It 
also updates fish from version 2.0.0 to version 2.1.0.

The patch is pasted below, or you can find it at 
<http://frammish.org/fish-patch.txt>.
