Partial setting override

[sweatpantsninja]

I have the following nested settings:

Settings.cloudant.facebook_database should always be "facebook_data", but in development, I get Settingslogic::MissingSetting: Missing setting 'facebook_database' in 'cloudant' section

It seems as if it overrides the nested hash entirely, rather than merging it.

Yes the hash is overridden instead of being merged and I found that to be a big problem too. @binarylogic please look closely at this issue and implement some kind of deep hash merging. BTW we are not the first who experienced this, look at #21 #16 (actually provides partial solution to this problem)
