Accept --chain and --base-path from command line

[gagarin55]

As a user I expect something like:

emerald account new --base-path=./ --chain=eth

[ghost]

Just as a supplement to working emerald --base-path=. --chain=eth account new?

Yes, right. Currently it reads the path from env variable, but should be able to get as an option too

But, the console already supports this option explicitly, try for example - emerald --base-path=abc --chain=eth account new [1]?

Environment variable is taken only if the --base-path option is not specified explicitly - https://github.com/ETCDEVTeam/emerald-vault/blob/master/src/cmd/mod.rs#L39

AFAIK there was a problem in some of the cases when it didn't accept it from command line. @gagarin55 can provide more details

May be it was wrong sequence, for example emerald --base-path=. ... works, but emerald ... --base-path=. isnt't. It works only if options stay before command, not after. But anyway, I am waiting for more details.
