Sudo Prompt: add common user name. Currently we use the exact user name. This is a parity issue with the native prompt. See screenshots.
Steps to Reproduce:
1. Delete Node.js.
2. Open Titanium Studio.
3. Titanium Updates => Install Node.js.
Titanium Studio sudo prompt appears using exact user name.
Titanium Studio sudo prompt appears using the common user name, as it would with the native osx sudo prompt.
