Use FlowLayout instead of QGridLayout in QtEmojiGrid
FlowLayout is an official BSD-licensed Qt example showing
how to implement custom layouts. It will layout items
dynamically in rows.
This way we don’t need static column/row calculations for
QGridLayout and it looks better.
Test-Information:
Build and ran on macOS 10.12.3 with Qt 5.7 to test that it has
a better, less spacious look.
