feature: validation of changes
Merge branch 'plugins_hooks' of https://github.com/codename-/jquery-handsontable into validator
validator - callback instead of return; this pointing to cellProperties
fix for regexp and some tests for that
validator can reject changes
bugfix: autoColumnSize did not take `<table>` class into account when measuring the column width
performance: use `cloneNode` in cell built-in cell renderers for better performance
add `grunt-contrib-connect` to `Gruntfile.js` that allows to run an ad-hoc http://localhost:8080/ server with command `grunt connect`
Merge branch 'cloneNodePerformance' into 0.9.5
