Load fixture files individually

[ebarbeito]

I wonder if it would be possible to load fixtures individually.

Adding a new --fixture option that let you load a single fixture file specified inside config.yml

This could have some benefits:

• Flexible data population in a very new database
• Periodic data loads of specific entities, purging the old data and importing newest from the current fixture file (this can be a modified version each time you make the data load).

If you think this could be useful I can start to give it a try.

Not sure what you mean by individually, is it a single fixture inside of a file, or a single file?

Feel free to send a PR for that yeah.

I was reffering to a single file. Issue title edited

I won't personally develop the feature, but if this is something you need I'll be happy to review and merge it.

I do this by assigning each fixture file a unique tag and then importing this tag
