add force_encoded_color flag to the data layer and warn about mixed encoding

Just started trying to use encoded dbs again, and after re-creating a new encoded database with the latest caffe-dev (which I see is now deprecated) the problem persists - so this doesn't seem to be a problem restricted to older databases.. even newly created DBs need the flag to force it. Would advise testing this on a dataset with mixed image encodings - I'm using the original imagenet images (without them being re-encoded) and finding this. |

You are right. I was trying to be a bit too smart about it in |

This PR fixes issue #1901, where older encoded DBs are not compatible with PR #1878. It adds a force_encoded_color flag to data_param, to force mixed encoded DBs to be read properly (as all color DBs).
It also warns users against the use of mixed color-gray DBs.
