[MAINTAINER UPDATE] www/sblg to 0.4.15

This is another simple maintainer update of sblg from 0.4.14 to 0.4.15.
The changes listed by the author are:

"Introduce ${sblg-has|key}, which tests whether key has been set (e.g.,
data-sblg-set-key=foo). If it has been set, emits sblg-has-key, or
nothing otherwise. This is useful for classes whose children will be
masked depending upon the existence of a key. Properly show dates in UTC
instead of localtime. (Unless asking for localtime.)"

I did testing on amd64 with no issues. I expect it should work fine
everywhere. If someone could ok and commit, that would be great.
