Refs #248: convert Polar template to Zepu template

There are 3 differences left between pageLayout.ihtml from polar and pageLayout.ihtml from zepu, see http://www.diffchecker.com/7i1ydnzu or attached screenshot.

If we add these 3 differences in zepu template, then the templates for pageLayout will become identical.
