Markdown rendering bug

[jeremysinger]

In tutorial.md file, I can use triple backticks to indicate JS code blocks. If I use the less-than symbol (e.g. in a for loop condition, i<10) then the less-than gets transformed to the HTML escape code < - which makes the code unreadable (and incorrect). Need to fix markdown rendering for code blocks.

This is also a problem with '<' and '>' in initialcode.js files, when we reset the code window to get back to the original code - we see HTML escape sequences instead of '<' and '>' - e.g. in for loop conditions.

erk, and sometimes in the textarea for the code, a '<' character is treated as an HTML open tag and the rest of the code disappears! This is a serious issue.
