Add an option to the Show History panel to show/ hide merges when running the search. This is very useful in large repos
where you tend to have a lot of automated merges being put back into the repo, that really have little information
content when looking at the history.
Will put a checkbox beside the current Search| Diff buttons. The setting will be global and persistent, defaulting to
Show Merges initially.
Added Show Merges checkbox to Show History, Incoming and Outgoing. Need to enable search in Incoming and Outgoing for
this to be really useful, this is logged as #126903.
Also outputting search context to repo tab.
