path to juliet.jl in Console.jl corrected to work on case-sensitive fs

Hey there,

I've just cloned the repository, compiled (under Kubuntu 12.04 64bit) and started JuliaStudio. I got an error that share/qtcreator/Juliet/src/Juliet.jl cannot be found. Turned out the path to the file used an uppercase character share/qtcreator/Juliet/src/Juliet.jl while it should have been /share/qtcreator/juliet/src/Juliet.jl

Fixed that and the wonderful JuliaStudio worked as expected.

best,
Georgi
