[Frontend] channel land

[b-g]

• missing big tooltip channel details (yield via click on channel dots in map)
• zoom/reset control of map are not working
• hover tooltip channel dots, width of the tooltip is sometimes not wide enough for long channel names e.g. "#Ergonomic Granite Keyboard" (width of tooltip is ideally dynamic in relation to text length)
• channel names search should grey out not found ones, see 2 mockups/3f.png
• if map is zoomed in dot sizes should adjust size become slightly bigger.
• missing "back" button, left of page title
• missing groups control
• mouse double click on map should zoom in
• zoom in/out with scroll gesture doesn't work 100%, seems to be contradicting with page scrolling (if mouse is not over a viz element of the map)
• update footer, see #25
• map zooming and dot sizes, size changes should be smooth (if possible and not too much effort)
