Massive update 3.5

Up to 500+ mods in 1.7.10. The next step: Beat the 1.5.1 record.
Notes:
Search for "Description needed." you should work on it :smile: 
Also check "Staircraft" description -> "Adds dds" "dds"? :smile: 
Rei's Minimap 1.6.2 not working on 1.6.4 (atleast for me) so I've added 1.6.4 version.
