Keep resolving #4

`innerHTML` is gone from LER.js by using `json2dom`.
But I just found that extended `parseInt` in parseInt.js also uses
`eval`, which is forbidden by Mozilla.

(Chrome only) Add a new tab in popup window  for single article to
全國法規資料庫.
Editing `parseInt`

For #4 since `parseInt` uses `eval`; not done yet.
