Add "bulk mute/unmute/block/unblock" feature

As another part of #227 (closed), this will add a bulk feature to mutes/blocks tabs.

Technical notes;

• Replaced withList HOC with List component since component composition using slots is more flexible than HOC for the list purpose and also it is the preferred way of Vue.
• Added reusable Checkbox, ProgressButton and SelectableList components.
• Moved line style for splitting list items from BasicUserCard to List component.
