Initial TrialBalance room (room #6)

Using the journalRoom.js as a model, create an empty but working "Trial Balance Room." You can find the journalRoom commits on the iss_157 #157 branch. My suggestion is to the checkout that branch, then create your new branch for this issue OFF OF THAT ISS_157 BRANCH. That way you get all the journalRoom stuff.

What to do:

- [ ] copy journalRoom.js to trialBalRoom.js
- [ ] Change quoted text "Journal" to "Trial Balance" etc. (Learn how to search in your editor!)
- [ ] Change all room4_ references to room6_ instead
- [ ] Change all Room4 folder and filename stuff to Room6
- [ ] Create asset folders for Room6 and Panels/Room6
- [ ] Find a "floor" image for the TrialBalance room that is unique to our game
- [ ] Update images so that each of the 6 wall panels has one (not two or three like in journal room)
- [ ] Update various locations for the wall panel stuff (scaling, alphas, etc.)
- [ ] Update roomProgress values from 4000 based to 6000.
- [ ] Change read ordering of the wall panels in the interactivity function.
- [ ] comment out most of the checkNextPages (I think that's the name) function
- [ ] update main.js and index.html so you can test this initial room out (Accacio moves around and can read the default wall panels)

Anything else needed that I forgot? Add as a followup comment below.

まず iss_157 #157 ブランチをチェックアウトして journalRoom.js を読み、それを trialBalRoom.js のモデルとして使用します。参照されている Room6 アセットの場所、main.js、index.html を更新します。Trial Balance ルームが読み込まれ、Accacio がその中を移動でき、6 枚すべての壁パネルに読み取り可能なデフォルトコンテンツが表示されれば完了です。
