Project name splitting prevents mixed case matches

[ocrow]

The fix for #5 substring matching results in confusing behavior for projects with mixed case titles. For example, if I have a project named "JZnum" (read "JZ num"), typing "st jz" no longer matches that project. The camel_case_split() call converts the project name to "J Znum", for the purposes of matching. One must type "st j z" to match the project, which is quite counter-intuitive.
