allow jumping directly to changelist by hash

Describe the feature that you'd like Currently the search box works only on commits that are actually loaded in the git graph window. Going to a commit from a month or a year ago may take a lot of scrolling, to reach the approximate time frame and only then use the search box with exact hash.

If this would be added it would be a huge improvement.
