Fixed broken .cpp highlighting.

It was returning "h++" non-existent highlighter for "cpp" extension, while it was supposed to return "cpp" for "h++" extension.
Highlight with `plain` for unknown extension.

Right now files with unknown extension are not highlighted at all, so they have no line numbers and inconsistent font/look with other views.
Use same font size as for diff (1em everywhere).
Source view gutter now consistent with diff.

Using gray less intrusive gutter, that lines up nicely with the rest of app UI.
Line up blame view gutter with others.
