Codemirror 程式修改

1. 先列出修改前後，有那些檔案被更動，再逐一說明。結果只有二個檔被更動過。

   [root@dywang moodle23]# diff -qrwbBE mod_tmp/codemirror-3.19 lib/form/codemirror-3.19/
   Files mod_tmp/codemirror-3.19/lib/codemirror.css and lib/form/codemirror-3.19/lib/codemirror.css differ
   Files mod_tmp/codemirror-3.19/mode/python/index.html and lib/form/codemirror-3.19/mode/python/index.html differ
   

2. 修改 CodeMirror CSS 顯示樣版，增加捲軸設定，最小高度 4 行，最大高度 30 行。

    .CodeMirror span { *vertical-align: text-bottom; }
   

3. 因 python 程式以內縮判讀程式區塊，建議以 TAB 內縮對齊。所以先修改 index.html 增加 enterMode: "flat"，讓 codearea 按下 enter 產生新的一行時，不會自動加入「空白內縮」。
