Divergence from base branch display (#3613)

- **PR Description**

Add a new config option `showDivergenceFromBaseBranch`; if not "none",
it indicates in the branches view for each branch if it has fallen
behind its base branch, and optionally by how much. If set to
"onlyArrow", it will append `↓` after the branch status; if set to
"arrowAndNumber", it appends `↓17`, where the count indicates how many
commits it is behind the base branch. These are colored in blue, and go
after the existing yellow `↓3↑7` indication of divergence from the
upstream.

The option is off by default, since we are afraid that people may find
this too noisy. We may reconsider this choice in the future if the
response is positive.

- **Please check if the PR fulfills these requirements**
