Fix word case issue

Problem with two files in repo with same name, but diff case
Fix by git mv -f
renamed:
drivers/firefox/data/images/icons/Wordpress.png ->
drivers/firefox/data/images/icons/WordPress.png

Solution from:

Show page errors only in verbose mode

Phantom sent page errors to stdout, becuse no handler assigned.
I add page.onError handler, which use wappalyzer.log [debug] output
