Title: Hotkeys: use Ctrl+C to copy commit hash to clipboard

...which implied the following:
- change default setting: GoToParent (Alt+P, instead of Ctrl+C), GoToChild (Alt+C, instead of Ctrl+C)

Slightly off-topic: add default key setting for ToggleHighlightSelectedBranch: Ctrl+Shift+B. What do you think?
