BREAKING CHANGE: OPTION PROJECT NOW PROJECTS.

Can now specify multiple projects for a given command. Especially useful for timelog, or timesheet management. N stuff.

Also added --totaltime flag (aka -l) for list command, which will output the list of anything not Sub-task as a list of estimates, total times, and time spent. This could become prettier but it serves my nefarious purposes for now, so I really don't want to touch it right away.

Cheers!
