Bug description:FILTER_VALIDATE_EMAIL fails on numeric TLDs

Description:
------------
Although FILTER_VALIDATE_EMAIL accepts non-existent TLDs, it refuses to
validate 
numeric TLDs.

AFAIK, there is no technical justification for this: numeric TLDs just work
out of 
the box as far as the DNS know about them.

I suggest that the filter should validate numeric TLDs, or that a 
FILTER_FLAG_ALLOW_NUMTLD be created to alter the default behaviour of the
filter.

Test script:
---------------
filter_var("johndoe@domain.123", FILTER_SANITIZE_EMAIL) ; // returns false
