webif: Make CSS, JSCRIPT and TOUCH_xxx a proper templates.

Now we have only one way of dealing with resources - everything
is in templates array. We can use /savetemplates.html to extract
CSS, JSCRIPT, etc, we can replace those as any other template and
so on.

The road to generating module-webif-pages.c from the build system
is open.
