'eosio-init -p xxx' should camelize argument when make a contract skeleton

[drunkhacker]

This line uses the argument passed from eosio-init -p without sanitizing or such. If I pass a Kebab case string e.g., 'hello-world', this will create CONTRACT hello-world which is not valid name for a class.

It'd be good to camelize the input string or prevent the string cannot be used as identifier in C++.
