5.0.0

Fixed

• #136. frame
  command not working with negative numbers (thanks @ark6).

Added

• IDE support and a new command/subcommand API for plugins.
• Add a "savefile" setting holding the file where "save" command saves current
  debugger's state.

Changed

• disable no longer disable all breakpoints, it just shows command's help
  instead. To disable all breakpoints now you need to do disable breakpoints
  (or dis b). Similarly, you can't no longer use dis 1 2 3 but need to do
  dis b 1 2 3 to disable specific breakpoints. The same applies to the enable
  command.

Removed

• help set <setting> no longer works. help set includes that same output and
  it's not verbose enough so that this is a problem. Same with help show <setting>.
