When the network connection is changed, the sticker packs are cleared and then re-loaded (either loading the offline (installed) sticker packs, or all the sticker packs from the network).
Stickers can be sent while offline, though the sticker images do not load once offline (this is likely a side effect of the bug described below).
There is a known bug in QNetworkAccessManager (https://bugreports.qt.io/browse/QTBUG-55180) that was re-introduced in 5.14.1 that does not allow us to download resources if we go offline then come back online. The workaround employed in this PR manually sets the NetworkAccessible property of QNetworkAccessManager once we have been connected back online. The NetworkAccessible property is marked as obsolete and will be removed in Qt6, so it is something that we need to be aware of when we upgrade. However the hope is that the bug has been fixed.
Close StickersPopup when disconnected from network (so that re-loading of sticker packs doesn't look out of place).
fix: set network status correctly at load
feat: stickers gas estimate async
feat: When network re-connected, any http images that were not properly loaded in an ImageLoader component will automatically be reloaded.
fix: Sticker button loading icon

Adds a loading state to stickers, so that a loading indicator appears while the sticker is being downloaded from IPFS.
In the case of a network failure or timetout, a reload button is shown instead. Once network is restored and the reload button is clicked, the image is reloaded from the network, going through the same lifecycle of showing the loading state first.
