Bad username formatting with special characters

[luxaritas]

For example, logging in with a space at the end of your username winds up adding %20 to your username, even though it is accepted for a login. Really, the "correct" username should be gotten from the API.

Edit: Per https://github.com/EteRNAgame/HTML-Chat/issues/39#issuecomment-293789894, this is the full extent of how this issue needs to be solved

• [x] decodeURIComponent needs to be used when getting the username parameter from the URL of the iframe (https://github.com/EteRNAgame/HTML-Chat/commit/f31a32a7176ded86e9d2f5108c14a7d78052e235)
• [x] The webpack dev server needs to be updated to use the API, so that things like capitalization and adding extra spaces doesn't happen when logging in from the test page (https://github.com/EteRNAgame/HTML-Chat/commit/e496d5a6ca4aacc5f7d8e4dcb9ab35e532e6f29a, ca358a1fec9f6eeb9b3461d010c84be228cdcd42)
• [x] The server on irc.eternagame.org needs to be updated similarly
• [x] The test page needs to actually use the username which the server will return (https://github.com/EteRNAgame/HTML-Chat/commit/e496d5a6ca4aacc5f7d8e4dcb9ab35e532e6f29a)

Kudos to Astromon for finding this one.

Fixed in #42

Oops, this was not fixed - wrong issue!

Just realized that this doesn't just apply to the test page. There are three things that need fixing:

• decodeURIComponent needs to be used when getting the username parameter from the URL of the iframe
• The webpack dev server needs to be updated to use the API, so that things like capitalization and adding extra spaces doesn't happen when logging in from the test page
• The server on irc.eternagame.org needs to be updated similarly
• The test page needs to actually use the username which the server will return

(Edit: Added the task list to the first post in the issue so that it can be tracked)
