/** \fn KeyBindings::GetConflict(const QString&,const QString&,int&) const
* \brief Determine if adding a key would cause a conflict.
* \param context_name The name of the context.
* \param key The key to add.
* \param level The level of conflict if this returns an ActionID
* \return pointer to an ActionID if adding the key would cause a conflict.
*
* Conflicts occur if:
* \li the key is a jump point, but is bound elsewhere
* \li the key is already bound to a jumppoint.
* \li the key is bound to something in the global context.
* \li the key is bound to something else in the specified context
*
* If the method does not return NULL, check the value given to
* level. Warnings can be ignored (at the users disgression), but
* errors should be prevented no matter what.
*
* NOTE: If this returns a non-null pointer, the ActionID returned
* must be explicitly deleted with C++ "delete".
