add "Update issue" action to

[k2s]

In line gutter there is "Update issue" action if issue for this line already exists.

When using the botom reVu panel with list of issues on left, it is possible to update issue on the right, but the form is much smaller then when opened as dialog from line gutter.

It would be nice to have toolbar icon "Edit in dialog" next to "Jump to Source" icon.
This action would be nice also on right click menu in issue list (left panel).
