New sourcecode formatting

Thanks to Alf, I have discovered the WordPress [sourcecode] tag. Where I would previously use <code> and <pre> and get the following result:

int true_random() {
    return 4; //Generated by fair roll of a die
}

I now use [sourcecode language="cpp"] ... [/sourcecode] and get the following:

int true_random() {
    return 4; //Generated by fair roll of a die
}

The syntax highlighting and line numbering is done client-side with JavaScript, but even without JavaScript the code looks nicely formatted with <pre>.

I have gone through all my older posts and updated them to use the new tag, please let me know if you see any spots I missed, or any errors I made in the process.
