Add keybinding option for all build commands

[cas--]

In the Build Commands dialog there are additional commands under Conf commands, Independent commands and Execute commands that are not available to setup in Preferences|Keybindings. It would be very useful to be able to set keybindings for these. Further to this the command names in Build commands can be modified but this is not reflected in Keybindings preferences.

Just a quick thought too; a button linking to the keybindings prefecences would be a helpful addition to the Build commands dialog.
