Introduced Style.svg() Style.png() Style.emoji() and
Style.icon() in Style.qml. Those should be used to
set the source in Images instead of using relative
paths. Usage:
Image {
source: Style.svg("check)
....
Also moved all Singletons inside a new "utils"
folder and made it a QML module, to use
import utils 1.0 instead of relative paths
Closes#3678
Toast message is added when user access an existing community using community's private key. Toast
message with message that importing community is in progress is displayed while community is being
imported and once it is imported toast is closed and new one, which will be closed in 4 seconds,
with message that community is imported is displayed.
Fixes: #2467
