Print template parsing errors to aid troubleshooting

Added a new Template.PrintErrors() function call,
used in hugolib/site.go#Process() so it does not clutter
up `go test -v ./...` results.

Special thanks to @tatsushid for mapping out the call trace
which makes it a lot easier to find the appropriate places
to place the Template.PrintErrors() call.

Fixes #316
