Add flag for Y/M/D tree creation

[stuartcampbell]

I've added a field create_ymd_directory_tree which will globally default to false but is set to be true for detector (and default) directories.

The new response from the API is in an attachment in a comment below.

resolves #32

Should we make this an enum, to lay track for possibly creating finer trees in some cases, like yyyy/mm/dd/hh? We have cases on the floor where directories are too large.

I think this is a great idea - have the enum specify the level of granularity, like create_ymd_tree: <none|hour|day|month|year>

[stuartcampbell]

For clarity, are we saying that we would have one value and that would be the lowest level of granularity, e.g. if we specify month we would create assets/default/$YEAR/$MONTH/ or are we wanting a mask type thing, where if you want down to month you would specify both year and month ?

I think going with what @nmaytan suggested (i.e. <none|hour|day|month|year>) is fine and this specifies the most granular level we create, I just wanted to make sure we were all on the same page.
