Edits Contained in this Pull Request:
logic.php - adds the meta data options for GCF and IEedge.
templateDetails.xml - adds template parameters to control the use of GCF and/or IEedge.
en-GB.tpl_frontend.ini - language items for GCF and IEedge parameters.
de-DE.tpl_frontend.ini - this contains the English items for GCF & IEedge parameters because I don't speak German so Alexander or someone else will need to translate the items.
index.php - this solves the issue of people seeing a blank page...now they will just see unstyled components.
