Subject: luci-base: form.js: rework section add/remove event handling
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=745878d6cd5aa498916cea13d6887d500bc5c32b;p=project%2Fluci.git

 - Redraw map even when it could not be saved due to validation errors
 - Use createHandlerFn() for attaching event handlers
 - Convert buttons to <button> element to allow use of spinning class
