Fix module import path for package

[jeremydw]

Currently, the packaged import path includes the "src" directory, for example:

import {PluginComponent} from '@amagaki/amagaki/src/plugins';

We need to change our release process so that the "src" directory is removed:

import {PluginComponent} from '@amagaki/amagaki/plugins';

This has to do with how the TS compiler happens. I believe that you need to point it at the compiled JS, not the TS for importing from another library.

ex: src/index.ts compiles to dist/src/index.js which when used as a library becomes import {something} from @amagaki/amagaki/dist/src/index.

If you figure out a way to do this without co-mingling the compiled js at the root directory let me know :)
