Need to be there for manual edits.
All custom edits gets their own lines, so character highlighting is unnecessary.
- Use actual patched value - Copy over source also if it is not present on patch op itself (typically for pushed patches)
Don't try to replace text if already synced (will lead to invalid value).
Don't apply mixed chunk borders on top of custom chunks
The value of `cm.getValue()` was previously not well-defined if multiple changes had occurred within the same operation (e.g. a newline followed by an automatic indent). By reconstructing ourself, we should be OK as long as model stays in sync!
Assumed not to be critical. If reverting, some of the manual edit alignment might be off, as line chunking becomes unreliable.
Always choose the simplest diff.
If you undo a manual edit by using the pickers, the decision should be deleted unless there is a local/remote diff. If all decisions of a chunk are removed, the picker should be removed as well.

This PR should add proper support for manual editing in the merge pane of the merge view.
This isn't completely ready for merge yet, but it is good enough to share, and to recruit help in breaking it in interesting ways. Indicators for breaking: edited text becomes incorrect; an error notification pops up complaining about model/editor out of sync. Alignment issues are not critical for the end saved result, but might indicate that the decisions/diffs are a little wonky (and might therefore be easy to break with subsequent edits).
Currently this is only supported for a four-way merge view, so I also added a "force four way view" button to the header of all cells that are not four-way. In the future this might be solved more elegantly, but this gets the job done.
Fixes #195.
