v0.8.0

• [BC] Rename Gitify install:package to Gitify package:install, and Gitify install:modx to Gitify modx:install. Aliases are in place so they will continue to work for now, but those will be removed in v1.
• Extract instantiation logic out of Gitify file into application.php for easier integration with non-CLI PHP.
• Small speed optimization (~ 10%) to Gitify build --force (#78)
• Passing arguments to Gitify build and Gitify extract now restricts building/extracting to those specific data partitions/folders (#51, #26)
• Escape password in backup/restore commands so they work with special characters in the password
