Proper use of IDs and classes to enable better testability

jcechace: hpehl, basically right now I rely on xpath expressions when I want to select an element in selenium tests. Which you can imagine is not the most reliable thing
jcechace: hpehl, but the main premise is that every element important for user-app interaction should have id / class. One example - currently it is quite hard to select a table containing the list of resources and it's pager. Simply because those tables have class "default-cell-table" (there is usually like 4 of them).
jcechace: hpehl, not saying i can't select it, just that even a minor change in layout would break that selection
