nocopy option doesnt work without moving files (defeating part of the purpose)

#### Version information: 0.4.10

#### Type: Bug / Implementation Flaw

#### Severity: high

#### Description:
The "filestore" capability should be considered baseline for this project IMO. The expectation cant be to duplicate all bytes you want to place on IPFS by keeping a copy in the datastore... Nor can it be to expect users to throw their existing directory organisational structure out the window to manually copy IPFS candidate files to a central location.

Need the ability to --nocopy any file in any location and have that file not move or be copied anywhere. Also, if this --raw-leaves thing is needed for this it should be done by default. Not sure if it is though.

Thanks for your work on this world changing project.
