NumExpr patched from 2.6.3 to 2.6.4

[Robert McLeod]

This is a quick note to update from the release two days ago that we've
pushed NumExpr 2.6.4. The release of 2.6.3 two days ago omitted
implementations for the new `ceil` and `floor` functions for the Intel VML
when compiled with the Intel MKL.  Thanks to Christoph Gohlke for noticing
the error and patching it.

Also thanks to Matthew Brett for helping me to get the manywheels procedure
going for NumExpr. There was a minor delay yesterday in uploading due to
the Amazon/Travis outage.
