[Fixes #12] Add Browserify to build

[bluepichu]

Turns out the fix I had before was a full fix: the .d.ts issues I was having were due to setup errors on my end.

EDIT: No longer has any breaking changes.

---

The following no longer applies. I'm keeping it here so that the discussion below makes sense.

Breaking change: MultiStyleText is now wrapped in a module, which means that even when including this package via a <script> tag, you need to "unwrap" it to use it:

let textSample = new MultiStyleText.MultiStyleText("It's sad, but required.");

Hmm.. Why would this be wrapped into another MultiStyleText module?

Can't we just export the current MultiStyleText class?

[tleunen]

Is it necessary/useful to export the interfaces?

[bluepichu]

Yes, it's required - you can't export the MultiStyleText class if it has properties or methods that use types that wouldn't be accessible externally.

[tleunen]

I thought tsc was already compiling down to basic JS. Could you explain why browserify is required here?

Also, I'd like to find a way to remove the new wrapped module to remove the duplicationMultiStyleText.MultiStyleText when the file is injected in a script tag instead of using a commonjs require/import for example.

The point of Browserify here is to export the module for CommonJS and AMD if either of those are being used, and otherwise defaulting to a global export. This is similar to how Pixi itself functions (and they also use Browserify to build). I was originally hoping we could get away with using TS's umd module mode, which handles both CommonJS and AMD properly, but it doesn't default to exposing the module globally if neither is found.

I'd also like to remove the "double wrapping" problem if possible, but I couldn't find a way to do so. (In particular, I would've expected that export default class MultiStyleText would do the trick, but that instead exports the class to MultiStyleText.default.)

I'll keep looking into it.

I found a solution. I don't love it (it's kind of a hack), but it works. See TypeStrong/tsify#105.
