Lowercase all files/folders in excalibur

[eonarheim]

Steps to Reproduce

Issue is detailed here #1123, default semantics for imports.

Specific comment https://github.com/excaliburjs/Excalibur/issues/1123#issuecomment-483004520

Importing a barrel is clumsy because of the capitalization. This will cause breaking changes in folks using capitalized import paths. Also this tricky to change on windows because of it's case insensitivity in the file system.

Expected Result

Importing files should follow the best practice and standards in JS/TS.

Index.ts should be index.ts which is the conventional way for module resolves to be handled. It can alternative partially fixed by doing import {PointerEvent} from 'excalibur/dist/Input/Index' but then you get compiler errors saying that Document isn't a property of undefined on PointerScope for whatever reason.

Actual Result

Index must be explicitly stated in the import

Environment

• browsers and versions: All
• operating system: Windows
• Excalibur versions: master

Current Workaround

Import the barrel directly like this import {PointerEvent} from 'excalibur/dist/Input/Index'
