Fixed template to use phploc 2 format

I have noticed that csv generated by phploc uses LLOC instead of NCLOC for average number of strings. Because of this the plot group "G - Average Length" has no plots at all. Also there was a typo in a group "C - Testing", and also, to generate the "number of tests" metrics, you need to pass a "--count-tests" to phploc, this has to be fixed in gh-pages branch.
