1. Renames color names in palette. Using names such as "primary" and
"secondary" that are in consistent with designs such as material,
bootstrap and metro UI palettes. It adds `color-` prefix on color
variables in line with Vue Design System.
2. Introduces necessary changes to follow the system color system
everywhere without using any other color:
- It changes tooltip background from black to darker primary
colors.
- It overrides unset styles from tree component
- It ensures footer has same color as top menu.
3. Removes opacity CSS changes to have better control on choices. To
achieve that:
- It introduces new "light" variants of main colors
- It switches to colors with different variants (e.g. in Dialogs it
uses primary color as button as it has variants that can be
activated on hover meanwhile on-surface color is single).
4. Styles a tags (anchor elements) globally for consistency
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.
