(Hopefully) fixes #1 for good now.

Seems like you can click even earlier now - once it was once per day, then it was once very 2 h, now every ca. 23 mins.
To be save I increased set it to 25 mins.

- Fixes #1 - Works for the new site layout now
- Also removed the const list of options, replacing it with a lookup of the link value which is unique for default buttons
- Changed from 4 to 2 spaces indentation
- Added periods to comment sentences

Didn't work anymore for a seemingly updated site, so I checked and they changed the button class name

- Added random delay before clicking the button after opening page
- Changed from [at]include to [at]match ([at]include seems to be more or less deprecated)
- Added configurable times in human readable format as constants on top

Probably there was an update for Christmas...

Done to avoid running before ready again.
Exactly 3 h is to little because of loading times, so better safe than sorry 0: )
