Import feature

[ReekenX]

Checked API docs, empty How To page, Github issues, Freenode channel. Strange that so far only export was requested, but not import.

I was thinking to move away from Toggl to Tomato.es just because this tool is Open Source. That would be easy if Tomatoes Params would receive created_at and modified_at I think.

This limitation is only to protect leaders board or something else?
