No longer searches nested projects (0.3.0)

[kfaustino]

I have recently upgraded PeepOpen to version 0.3.0 from the previous version.

The issue I am encountering is on large projects which have nested gems within the codebase. PeepOpen is not allowing searching of all files any longer unless you select a root project file.

A great example of recreating this is by using PeepOpen with Rails. If select a file within the project root, PeepOpen will find all the files within the project. However, if you go into a nested project, such as ActiveSupport and attempt to search for something in another project, like ActiveRecord, PeepOpen will only find files within ActiveSupport.
