add jinja2 dependency
minor cleanup
Moved feed templates to planet/templates since they do not change
Simplified 'techart' dir, moved config and index to root.
Updated run_planet to match, and added -v arg.
Got rid of page-specific section support.
Moved some constants into constants so it can be used by render and init without circular imports.
Broke render_template into implementation specific (htmltmpl and jina) functions, with common code in the chooser function.
Jinja2 is working :)
Switches based on template extension.
Required some fun encode/decode stuff because the two engines handle unicode differently.
Moved more stuff into the common function.
Needs documentation now that stuff is working.
