App-level Config / code style

Browse Source 
config.json now controls encryption and salt for both passwords and
forms authentication; data-config.json options are now under the "data"
key in config.json.

Unaligned ->'s throughout code per F# design guidelines, pulled out some
longer lambdas into their own let bindings within the method/function
scope, added qualified access attributes to smaller constant-type
modules
