Add phploc and phpmetrics

[kenjis]

I always use phploc and phpmetrics.
So I hope new PHP projects have them.

I exclude phploc from skeleton because it is like more for CI tools? (like document generator)
or you may need those tools at development. Thoughts?

I sent PR: bearsunday/BEAR.QATools#9

I see code size (LOC or xLOC) at development.
But yeah, it is also QA tool and is like more for CI tools.
