Allow using emoji name in macros.

[StrikerTheHedgefox]

Should set things up to allow using emoji names in macros.

Like so:

$.controls add :arrow_double_up: "sudo apt-get update && sudo apt-get upgrade\n"
$.controls add :arrows_counterclockwise:  "echo REBOOTING VPS...\nsudo reboot\n"
$.controls add :x: .close
$.controls add :card_box: "dir\n"
$.controls add :arrow_up:  "cd ..\n"
