Fixed page title and header image

Styles were loaded before $Header and $HeaderImg variables were set causing them to be blank on report generation. Properly set the variable replacements in the style templates.

Removed the settings section of 00 1st Plugin - Select Report Header.ps1 since, even though commented out, the question was still being asked during config which was misleading.

Before changes I've always gotten an empty page title and a broken header image.
