appview: proper nested templates master

This now allows for a more organized template structure. All templates can now be accessed via "parent/child" paths, and are templated atop the layouts/*.html files. The layout files themselves are modular and can be included in each other. The only caveat is layout/*.html NEED to define their own template names like so: {{ define "base" }} The other page templates do not (and musn't) define their own template.
