Error in strict mode

[RobertCordes]

I got two global var errors when using dropkick in strict mode. I fixed it by doing the following:

• In the for loop in the close method (line 316) I changed i = 0 to var i = 0
• In the open method on line 332 I added direction to the var list

PS: I was a bit intimidated by your "Contributing" section, that's why I didn't create a pull request ;) But I still wanted to let you know in case someone else has the same problem. When you have to double click the generated select field this fix should work.

Just out of curiosity what intimidated you?

Well, nothing about your contributing section in particular I guess. I just never created a pull request so I'm a bit unsure about this whole process and I don't want to do anything wrong or even break something ;) Still wanted to help, though.
