Add support for 'someday' directory, on same level as project directory, with all of the same functionality. This was always here but I wasn't using them correctly; this was inspried by GTD, and I'm now actively putting my current projects in 'projects/', and the rest in 'someday/'. Both appear in left side now, can have resources, etc.
Realized in last commit that not all users will have a 'somday' directory (yet); now avoiding displaying that text on the left side if the directory is empty (hopefully also works if it doesn't exist).
