cheasheets are searched for in the wrong directory after install

[adrianinsaval]

running micro -plugin install cheat installs it to ~/.config/micro/plug/cheat but the code is looking for cheat sheets in plug/micro-cheat/cheatsheets so they are always empty when using the command

micro-cheat/main.lua

Line 12 in 32d4fa3

local cheatdir = config.ConfigDir.."/plug/micro-cheat/cheatsheets/"

either the default install directory should be fixed to be micro-cheat or the code changed. I changed the code to fix this locally for me
