[MOD] bit of cleanup: removed shadowlayers as they are obsolete with bootstrap, changed div module-footer to bootstraps panel-footer and moved module controls there to visually clean up the module title area. also added close tag to module content toggle button to make the title look nicer when this pref is enabled

[MOD] no need to write theme name in the title, it is already visible in the dropdown (in other modules like switch language we also dont write the language name in the title)
