3 new options

Added 3 options:
- Uncolor messages, colored messages stand out to me and mostly they are annoying.
- Remove emoticons: There has been a flood of emoticons recently, removing them makes the chat much more readable
- Filter overly long messages: Filters out messages that (approximately) cover more than 4 lines
- Also includes the userscript fix (#85)

I don't understand why it lists all commits since March 3rd, in "files changed" it only shows relevant changes (from today) (and a random part of the custom filter (line 398-404)...?)
I suppose this is because gh-pages was last updated without merging from master?
