Substantial rework of sunpop.cn 'app_dynamic_list' module to achieve compatibility with odoo 11 and 12

This moduld allows user to customize columns dynamically in list (tree) view of any object of any installed module.

"Set Columns" button contains all field(s) in dropdown with checkbox which will exist in list view of current object. So if user wants to show/hide any field, then he/she has to just do check/uncheck that respective checkbox besides field name in dropdown list and then just click on "Apply" button.
