Add test to check if select component elements is equal to the items in the cubeviz-component-setupComponentElements list
Redesign select component elements dialog
Some ui nice ups in component; implement "sort by alphabet" button
Implement sortLiItemsByCheckStatus for associated button
Implement sortLiItemsByObservationCount function for associated button
Add CSS to make it visible what sort button was clicked
sort functions from CubeViz_View_Helper now return a modified list of values

- that makes it easiert to test instead of giving them real lists with li-elements
sort functions returns arrays with real copies of li items (most possible decoupling) and add test for sortLiItemsByAlphabet
Fix bug in sort functions result handling: re-add list.empty()
