"Add conditional breakpoint" on line with conditional breakpoint should edit the breakpoint

[roblourens]

Or, expose the command to edit the breakpoint.

I only set breakpoints with the keyboard, and I just realized that I can't edit an existing conditional breakpoint, or logpoint, with the keyboard.

• Add a conditional BP
• On the same line, run the "Add conditional BP" command
• It shows an empty input box and if you enter something, it will replace the existing breakpoint
