Incremental commit before I go home...
Basic tagging
'Fixed' form errors with datetime
Messing with WTForms
Markdown support via Flask-Markdown
Minor cosmetics things
Minor changes to installer
Learned about magic methods
Looked into Moment.js
Added more post types. Need to figure out filters and models for each...
Implemented very basic login with Flask-Login. Yay!
Can show all posts by tag
Can concatenate multiple tags with "+"
Multiple users can log in
	Roles is beyond the scope of this problem ;)
