-upgrade to latest griddly version
-refine keyboard & click navigation
-fix validation
-only show one editor at a time regardless of template
-cell underlying value attribute
-drop-down value support
-parse/format text
-save events
-implement destroy
-bind/unbind independently from create/destroy
-transparent editing while paging, filtering, sorting
-escape key resets to original value
