Simplify QML to work better on both Desktop and Phone

- Set request method to GET by default in ApiLocalConnectionHandler to avoid
/peers request fail randomly
- Use TabView instead of SwipeView to not depend on Qt 5.7.0 (latest version)
- AddTrustedNode simplified layout to avoid unexpected behaviour on some phones
- Locations add sslid property to root Item to avoid unexpected behaviour when
multiple locations are available
- TrustedNodesView color connected friends with green and offline with grey
- Ignore kdevelop 4 files
