In the html/layout panel, css display value of the current element shown

The main work is done in layout.js and layout.css files only. But I added "a11y.layout.display=display" line to all locale property files. I am not sure if my NetBeans harmed all these property files, converting chars to unicode sequences, as shown in the diff report. If it's harmed, reject me and I'll pull another request, including only layout.js and layout.css & without all these locale files.
