Support for stickers
Apparently the new sticker feature landed because everyone's using them. The aebruno version of Whisperfish sees a message has come through but doesn't show an attachment, shows them as empty messages instead.
This is problematic because Sailfish is apparently behind in emoji support, many emojis come across consisting of their constituent ligatures and/or placeholder symbols. Now unless the use of stickers is a toy for a while, it's even worse for Sailfish users on the whole :(
