Fixed a dumb bug where post-Early Idea Groups never became available. All Idea Groups now become available when they're supposed to (ie, Admin Tech levels 50 and 81).

For those curious: my regular expression wasn't excluding lines with "adm_tech = xx", which would cause the output file to multiply the required adm tech by 10, just like every other idea.

For example, in Extended Timeline the "vanilla" Idea Groups don't become available until Admin Tech Level 50. The old version of my script was changing that to Admin Tech Level 500, which doesn't exist. Extended Timeline only gets to 99. Ergo, this meant that you would never unlock post-Early Idea Groups.

Fixed thumbnail. Literally, that's it.
