Plugin to work without manual install

I just installed the Swift Lint plugin in AppCode.  I wasted about 20 minutes trying to figure out how to make it work, finding the install instructions, and then following them.  How about making the plugin work right away for new users?

1. Include the `swiftlint` binary in the plugin.  I want to use AppCode's plugin manager to keep the binary updated.
2. Automatically enable the inspection.
