[Feature] improve web client for mobile browsers

[aisbergde]

The feature

The web client works not bad also on mobile browsers. Some features, missing in the native app, are available. Some features are faster (map view). In other words, it is a good alternative to the native app.
Something could be improved for mobile browsers:

• detect, if screen is landscape or portrait
  • if portrait orientation, the information sidebar could be not on the right, but under the asset.
• show / hide information part - support for swiping would be fine (swipe up - show info, swipe down - hide info).
• improve sync settings (web browser - android browser)
  • take into account sidebar settings (for example, I enabled "People", they are shown in the desktop browser, but in the settings in the mobile browser there are enabled).
    Are these settings not saved in the database, but in the browser cash? If I change them in a desktop browser, these changes are not recognized in the mobile browser.
    I enabled this option several times and lost settings. Something is wrong regarding this option and saving it's state.
