Eclim install fails when there is a space in the path to Eclipse.

[andrewstein]

Have the following issue:

$ ./eclim_2.8.0.bin
Welcome to the installer for eclim 2.8.0.

 Please specify the path to your Eclipse.app directory.
   Ex: /Applications/Eclipse.app
       ~/Applications/Eclipse.app
 > /Applications/Eclipse\ Java.app
 No such directory: /Applications/Eclipse\ Java.app

Variations such as "/Applications/Eclipse Java.app", "/Applications/Eclipse\ Java.app", etc. don't work either.

This is similar to #562, but not quite the same
