Default to 'content' variable for content block
Upgrade to Foundation 4.0.8; replace static assets
Add minified JavaScript libraries (JQuery, Zepto)
Add Fundatio.init_app() docstring
Add FUNDATIO_JAVASCRIPT_LIBRARY config setting
Update CSS/JS refs in page template to Foundation 4
Correctly load jQuery/Zepto and Foundation JavaScripts
Drop minified Zepto

The minified Zepto library included before did not include some of the
features used by Foundation (e.g. fade out effects). Instead use the
unminified Zepto library as distributed in the Foundation tarball.

(Note that the bundled jQuery is still served minified.)
Add 'data-alert' attribute to alert box markup

The close button does not work in Foundation 4 if the 'data-alert'
attribute is not set.
Rename 'javascripts' block to 'javascript'
Use jQuery by default (instead of auto detecting)

Zepto is not compatible with all browsers, so jQuery seems a safer
default. The FUNDATIO_JAVASCRIPT_LIBRARY config setting can be set to
'auto' or to 'zepto' to force auto-detection or Zepto respectively.
Drop button macro

The button macro seems a useless indirection. The actual Foundation
button markup is actually quite easy to read and write directly. A macro
with semantic attributes that translate directly to CSS classes doesn't
get us anything but verbose code. Furthermore, the now removed button
macro only supported <a> tags, which rendered them useless for forms.
Update to Foundation 4.0.9
Add blocks to override Foundation JavaScript defaults

Two blocks 'javascript_foundation' and 'javascript_foundation_init' can
be used to override the included foundation.js and the call to the
$(document).foundation(...) routine in child templates.
Don't try to be smart about whitespace

Since there will be plenty of whitespace and many empty lines in the
resulting HTML anyway, don't even bother "fixing" a few of those.
Wrap jQuery/Zepto loading in 'javascript_library' block
Cleanup alert() helper macro
Add form rendering macros label() and field()

These macros can be used with WTForms to render fields and labels.
Add Foundicons web fonts and CSS files
Add support for icons from the Foundicon sets

Icon sets can be loaded by specifying a list of names in the
FUNDATIO_ICON_SETS configuration setting. A small CSS file is added to
handle CSS class names. Using these is required when using multiple
sets; see the Foundicons documentation.
