Use correct variable name

Fixes #58.

On lines 38/39 of index.js, the TOC's default state is set using the checkedState variable, which is passed to toc_entry.ejs. However, toc_entry.ejs reads the checked variable instead. This PR fixes that issue by using checkedState instead in toc_entry.ejs.

This does not fix it. checked is passed as per

eejs.require('./templates/toc_entry.ejs', {checked: checkedState}, module);

in index.js.

The actual reason for #58 is the urlContainstocTrue check in postAceInit.js. It calls getParam in toc.js, which checks for &toc=false in the URL, and if that's not there, unconditionally enables the toc, not regarding the setting.

I've updated the PR description to no longer say that it fixes #58. I'll leave the PR up because it does still fix an error.

args.content +=
eejs.require('./templates/toc_entry.ejs', {checked: checkedState}, module);
Is this still relevant. An object with checked is passed. So that should not be an issue.

I force pushed the branch just in case we need to merge it.

It does indeed seem like this PR does not solve any issues or bugs, so I'll close it.
