remove external guava-13.jar dependence

Right now the Acejump plguin have 1.6M size, but his core code only less 30 kb. 
The external guava-13.jar include because use one line Lists.reverse(...) [AceJumpAction.java:196] and i found an guava-12.jar shipped with Intellij or RubyMine(I don`t check WebStorm/PhpStorm but i think it should be the same.)

```bash
wyatt lib$ pwd
/Applications/RubyMine.app/lib
wyatt lib$ ll | grep gua
-rw-r--r--   1 wyatt  admin   1.7M Feb  6 21:04 guava-12.0.jar
```

So i remove the guava-13.jar and test with Intellij (plugin module) and it`s ok. 

Now Acejump plugin size from 1.6M to 30kb with no function lose, i wish you could consider about this.

PS: 
With `Mac OS X` or `Mac OS X 10.5+` keymap schema on Mac OS, `Project Structure` have the same keyboard shortcut(Command + ;)  should notice it.

Sorry for my poor english.
