No uppercase allowed?

[ebuchman]

I didn't seem to be able to get a flag with an uppercase letter in its name to work. Ie a config file like

myPort = 4444

is no good while

my_port = 4444

is fine.

A bug, needs to be fixed. While writing to ini file, we should convert camel case to its equivalent with underscores and vice versa.

Instead of trying to specially parse keys, why not just stop lower-casing them? If you were to take that approach, and someone wanted to store snake-case keys in the config file, when they pulled them out they'd suddenly be camel-case.
