Allow arbitrary command to generate commits for git-icing

HarveyHunt

I am using a script to generate commit hashes for `git cherry-menu` to use as such: ``` git cherry-menu ./my-script.sh ``` It'd be nice if I could use the same script as input to `git-icing`

Yeah that's a good idea. Currently use of `git cherry` is hardcoded into `git-icing`: ``` IO.popen(["git", "cherry", "-v"] + ARGV) do |out| ``` but it would be easy to change this. The only challenge is deciding the appropriate CLI syntax. I guess it could be changed to the same wrapper approach `git cherry-menu` uses, i.e. ``` git icing [icing options] COMMAND ARGS ``` where `COMMAND ARGS` is typically `git cherry -v`, although it means the most common usage invocation is a bit ugly: ``` git icing -v3 git cherry -v ```

Thanks for the quick response. :-) Would it not be possible to detect if no `COMMAND ARGS` sequence has been passed and just default to `git cherry -v`? That potential common usage invocation matches `git cherry-menu`, so perhaps the user might expect that behaviour?
