Jira/Bitbucket Smart Commit expect hashtag in front of magic word

[buep]

I just learned that the Smart Commit feature we rely on uses hashtag for commands.

So close should be #close and for say issues PRJ-17 our close message have to be PRJ-17 #close.

This is slightly different from Github.

We can try to auto detect the service the user is using, however it would be easier to use the configuration, since that can tell us directly what service you use.

So now wrap-up will work like this:

git phlow wrapup > using default conf or internal default

git phlow wrapup -t jira > using jira conf in .gitconfig
