refactor cli and gui wrapper code. Details:
- all cli functions shared between ethereum and ethereal abstracted to utils/ cmd.go (should be ethcommon or shared or sth) - simplify main() now readable stepwise - rename main wrapper files to main.go - rename commmand line args definition file from config.go to flags.go - rename Do -> Start to parallel option names - register interrupt for rpc server stop - fix interrupt stopping js repl and ethereum - register interrupt for mining stop - custom config file option from command line - debug option from command line - loglevel option from command line - changed ethutil.Config API - default datadir and default config file set together with other flag defaults in wrappers - default assetpath set together with other command line flags defaults in gui wrapper (not in ethutil.Config or ui/ui_lib) - options precedence: default < config file < environment variables < command line
