Title: Feature/show commit in main

I was missing the feature to show the (abbreviated) commit ID in the main view. The three commits in this branch implement this feature.

I have taken care to implement the feature, the settings including color for this feature, the possibility to toggle this feature and documentation for all of this.

By default the display is disabled, to not confuse regular users of Tig with a new default main view.

One question remains. I don't understand why need to use ``+1`` when drawing the commit ID to get ``7`` shown characters if the value of ``opt_id_len`` is ``7``?
