Edit default emojis
We use the default emojis and the custom emojis in our Mattermost. To custom it even more, we would like to edit the full set of default emojis (not create new ones) e.G. `:D`.
The proposition could be done in several parts:
- setup in the administration panel a way to edit the picture for one default emoji
- setup a way from the administration panel to import a set of emojis to replace the default ones
- setup in the administration panel a way to reset the default emojis to the original ones
- update mobile applications to display the edited default emojis instead of mobile's emojis.
