Massive update 4

Changelog:
- Removed a lot of dead(No download, etc) mods (Not mentioned in changelogs due to amounts :smile: )
- Added a lot of mods.
- Up to 600 mods in 1.7.10
- Added proper dependencies for some mods.
- Cleaned up mod list panel. (Still a lot of todo)
- This update doesn't require any descriptions.
- Some changes are not in changelogs. It is a big pain to add every small change to every version.

@GrygrFlzr I suggest you pull it today (maybe without changes if you have no time) and then, when you get some time, fix some issues if you find them. Also, what happened with Modlist twitter? Will it be updated any time?
