If we are syncing after having already completed the initial sync we do
not show the funding address QR code. In this case, adjust the title
padding so that the page title is better centred.
Rather than using relative paths for css imports - which can break when
we move files around - add our styles path to the webpack sass-loader
loader using the `includePaths` setting.
Handle the case were the Neutrino backend BTCd node is still
synchronising the blockchain as LND is not able to start syncing
until the BTCd node that it is connected to is fully synced.
