fixes #130 (and hopefully #159) - reassign proxy event argument fragments after a splice
tests for #130
closes #159 - splices that added and removed items simultaneously failed to update properly
rebuilt
fix recently introduced bug where array modifications broke two-way bindings
cleaned up Gruntfile
use jQuery for event tests
scrap jQuery, use simulant.js for tests - jQuery appears to fail with phantomjs and native event listeners
rebuilt
allow implicit iterators to resolve to the empty string (#161)
allow unconventional whitespace with attribute declarations in tags
closes #158 - button elements and input[type="button"] elements fire a tap event when they received a spacebar keypress while focused
