Support any fields in template meta comments
Right now it's allowed to place specially formatted block HTML comment on top of template to specify some fields of the category, that will be created based on that template. It looks like this:
<!--## <NAME>Page Name Here</NAME> <DESC>Page Description Here</DESC> <SECTION>Path To||The Page</SECTION> ##-->
This allows to auto-create all categories/sections for theme's template in right order during In-Portal installation. Such feature comes in handy during theme changes deployment on production/staging servers as well.
I'm proposing to expand this functionality by allowing any field to be set this way. On the other hand "any field" maybe is too powerful and developers might try to set the "Priority" field, which won't have any effect (because it's set internally already).
Alternative way would be to allow setting page url fragment (the "Filename" field). When set it would automatically turn off filename auto-generation. This would come especially useful for "index.tpl" page, where we always set "Home" as it's name, which results in "http://www.website.tld/home.html" url. For that template the hardcoded "index" url fragment is the best way to go.
