Template Usage Statistics in debug mode

*Title: Template Usage Statistics in debug mode

*Documentation:
The Template Usage Statistics feature in Exponential 3.6 makes it possible see 
the list of templates which were used to render a page.

*Settings:
To enable this feature make sure that your "site.ini.append" contains:
[DebugSettings]
DebugOutput=enabled

[TemplateSettings]
ShowUsedTemplates=enabled

*Design:
After that you will see a table "Template Usage Statistics" at the bottom 
of the page when you are browsing the site. This table consists of 
5 columns: "Template", "Requested template", "Full filename", "Edit",
"Override".
"Template"           - the name of template which were used.
"Requested template" - the name of template which were requested. "Requested
                       Template" may differs from "Template". For example: 
                       you have an override section which overrides 
                       "node/view/full.tpl" with "bla.tpl". Thus you will see 
                       "bla.tpl" in "Template" column and 
                       "node/view/full.tpl" in "Requsted template".
"Full filename"      - "design resource" + "requested template".
"Edit"               - will let you edit template using current siteAccess.
"Override"           - will let you override template using current siteAccess.
