removed not needed mu plugin and keep the dir by .gitkeep
renamed example env file and set WP_HOME without any protocol
set capistrano deployments to fit our architecture
restructured the gitignore and added instructions
moved application.php because it's not a configurable file and moved all app logic to the wpconfig
Removed duplicate declaration DB code because it was the same on all environments. Just set these in wpconfig and load the env variables there
