Add an option to define the default folder to open files/folders from

I can only comment on the Windows version, but when I choose File > Open Folder the path seems to start in the Sublime Text 2 folder in my User Appdata folder. I don't like to store my work in this folder, so I would like to be able to define my default folder or at least for the program to remember which folder I last opened (which it does sometimes, but is not consistent).
