52ed3570c4
This change updates our urfave/cli dependency to the v2 branch of the library. There are some Go API changes in cli v2: - Flag values can now be accessed using the methods ctx.Bool, ctx.Int, ctx.String, ... regardless of whether the flag is 'local' or 'global'. - v2 has built-in support for flag categories. Our home-grown category system is removed and the categories of flags are assigned as part of the flag definition. For users, there is only one observable difference with cli v2: flags must now strictly appear before regular arguments. For example, the following command is now invalid: geth account import mykey.json --password file.txt Instead, the command must be invoked as follows: geth account import --password file.txt mykey.json
