Detects clickable elements automatically and exempts them from
collapsing cards, also interacting with code area does no longer
collapse cards.
This commit also fixes subscribing to clicks on document every time card
list is loaded, but never unsubscribing. This impacts performance and
causes memory leaks. Now, registered event listener is removed every
time card list component is destroyed.
1. *Grouping* becomes *view*. Because *view* is more clear and extensible than *grouping*. It increases flexibility to extend by e.g. adding *flat* as a new view as discussed in #50, in this case "flat *view*" would make more sense than "flat *grouping*".
2. *None* becomes *tree*. Because *tree* is more descriptive than *none*.
Updates labels on top menu. As labels are updated, the file structure/names are refactored to follow the same concept. `TheScriptsList` is renamed to `TheScriptsView`. Also refactors `ViewChanger` so view types are presented in same way.
