Map: options should be available (or hinted at) in small map view

[tmfrnz]

Currently map options (such as changing opacity #21, selecting basemap #3) are only available when entering the full screen map mode, however the initially minified map does neither offer these options nor provides a hint that they are available in full screen (also see discussion here #21)

4 options 3 options to be considered

1. Offer all settings in minified view
2. Offer all settings in minified view but hide them by default, and show them when clicking a "settings" button
3. Include a hint informing users that options are available in full screen mode
4. Offer some settings in minified view with a hint informing that more options are available in full screen mode

Implemented option 1 for review
