Tries to detect and un-break Session IDs posted on 4chan

Tries to detect and un-break Session IDs posted on 4chan. It tries to semi-intelligently decide what's part of an ID and what isn't.

It may not produce a correct ID if the ID has other text interspersed like this...

05abcdef
Send me
a1b2c3
a message
9f8e7d
[...]

If an interspersed word contains only characters that can be interpreted as valid hexadecimal, (cafe, babe, dead, d00d, etc), it will be included as part of the ID. The script checks the ID length and tries to guess if the ID is valid or not, but mistakes can happen. You can always glance at the last 3-4 characters of the ID to make sure they match before you copy it.

If the first two characters of the ID (05) are split, the script will not recognize it as a Session ID. This is to minimize false positives elsewhere on the boards.

It should work flawlessly in any other case, regardless if the ID is broken up by spaces, newlines, underscores, anything.

As of 2.0, it also adds an option to remember copied IDs: Useful to avoid contacting the same user multiple times by mistake. The saved data never leaves your browser; Remembered IDs will be grayed out and underlined to denote that they've been copied in the past. To clear remembered IDs from your browser storage, simply uncheck the "Remember copied Session IDs" checkbox at the bottom of the page.

Works both with or without 4chan X. It also works on the FoolFuuka based archival boards archived.moe and thebarchive.com thread pages.
